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.
