wifi: mwifiex: Fix interface type change

Browse source 
commit a17b9f590f6ec2b9f1b12b1db3bf1d181de6b272 upstream.

When changing the interface type we also need to update the bss_num, the
driver private data is searched based on a unique (bss_type, bss_num)
tuple, therefore every time bss_type changes, bss_num must also change.

This fixes for example an issue in which, after the mode changed, a
wireless scan on the changed interface would not finish, leading to
repeated -EBUSY messages to userspace when other scan requests were
sent.

Fixes: c606008b7062 ("mwifiex: Properly initialize private structure on interface type changes")
