nr_hw_queues is always 1, because qedi set the num cqs after
qedi_host_alloc. It's a simple change to move this to before we do
scsi_add_host, but setting it seems to drop performance. It looks like the
problem is that there 3 locks in the main IO path, so we bash on them even
when nr_hw_queues > 1.

This patch just drops it for now why we work on removing those locks.
