529c95cc15 mac80211: brcmfmac: fix use-after-free & possible NULL pointer dereference
1) Using fwctx variable after brcmf_fw_request_done() was executed meant
   accessing freed memory.
2) Using fwctx->completion for the wait_for_completion_timeout() call
   could reuslt in NULL pointer dereference on fw loading error or if
   brcmf_fw_request_done() was executed quickly enough.

ac5a6acbb1 mac80211: Update to version 4.19.7-1
This updates the backports package used in mac80211 to version 4.19.7-1
which is based on kernel 4.19.7. This integrates all the stable fixes
introduces in this kernel version.

The deleted patches are not needed any more because they are either
included in the upstream Linux kernel 4.19.7 or in backports 4.19.7-1.

f208f77811 mac80211: fix brcmfmac on brcm2708
An upstream change broke brcmfmac when loaded with modparam roamoff=1.
As we are carrying a patch that enables roamoff by default on the
brcm2708 target to improve stability, wireless is currently broken
there. Add a patch to fix brcmfmac with roamoff=1.
