The following patches made apply over Martin's or Linus's trees. They
fix 2 use after free bugs caused by iscsi_tcp using the session's socket
to export the local IP address on the iscsi host to emulate the host's
local IP address.

Note that the naming is not great because the libiscsi session removal
and freeing functions are close to the iSCSI class's names. That will be
fixed in a separate patch for the 6.3 or 6.4 kernel (depending on when
this is merged) because it was a pretty big change fix up all the naming.

v2:
- Fix bug reproducer example in git commit message.
