[00/31] wifi: mwifiex: cleanup driver

This series has a bunch of cleanup and bugfix patches for the mwifiex
driver.

There's one topic which goes through the whole series: an instance of
the mwifiex driver is referred to as an adapter (struct
mwifiex_adapter).  An adapter has an array of struct mwifiex_private
pointers, each of them belongs to a virtual interface. Many functions
throughout the driver take a struct mwifiex_private * as context, but
are not specific to a virtual interface, but affect the whole adapter.
In many places where a priv * is needed but none is available the code
obtains a priv * by doing a:

	priv = mwifiex_get_priv(adapter, MWIFIEX_BSS_ROLE_ANY);

Depending on where it is used this is either a bug or could at least be
cleaned up. The driver currently has the send command function

int mwifiex_send_cmd(struct mwifiex_private *priv, u16 cmd_no,
                     u16 cmd_action, u32 cmd_oid, void *data_buf, bool sync)

This series introduces a second send command function which takes the
adapter as context:

int mwifiex_adapter_send_cmd(struct mwifiex_adapter *adapter, u16 cmd_no,
                             u16 cmd_action, u32 cmd_oid, void *data_buf, bool sync)

Many places in the driver are converted to use this function instead and
are also converted to take a struct mwifiex_adapter * as context
themselves which makes the code better readable.

Some places use this to obtain a priv *:

	priv = mwifiex_get_priv(adapter, MWIFIEX_BSS_ROLE_STA);

This will return the first priv that is configured for station mode.
Depending on the driver configuration there can be none or many privs in
station mode, so priv can unexpectedly be NULL or in case there are
multiple privs in station mode we might have to iterate over all of
them. This is cleaned up in this series.

The remaining patches are driveby catches I found when looking through
the code.

One patch worth mentioning here is "wifi: mwifiex: fix MAC address
handling".  Without it the mwifiex driver sets a new MAC address during
a change_virtual_intf operation which is pretty unexpected by userspace
and keeps the driver from working when a virtual interface is altered
from its default mode it is initialized with.

I've already sent "wifi: mwifiex: remove unnecessary priv checks" as a
separate patch, I included here again as this series depends on it, but
it's unchanged to the version I have sent earlier.
