Bug#867258: Compile fix with kernel 4.12

[koos vriezen]

Package: broadcom-sta-source
Version:  6.30.223.271-6

I use the attached patch to get this module compiled with 4.12. Works
fine for me the last few days.

Note, https://aur.archlinux.org/cgit/aur.git/tree/linux412.patch?h=broadcom-wl
patch is different. It calculates the bss field, as my patch only sets
the bssid field.
Please refer to
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=29ce6ecbb83c9185d76e3a7c340c9702d2a54961
all other driver fixes seem to be also setting bssid when bss not
already in scope. Also note that in the linux patch there where bss is
set when NULL (search for "info->bss = cfg80211_get_bss") the flags
differ.

Cheers,
Koos Vriezen
