mac80211: fix possible NULL dereference
If chanctx is missing on a given vif then the band
is assumed to be 2GHz. However if hw doesn't
support 2GHz band then mac80211 ended up with a
NULL dereference.
This fixes a splat:
[ 4605.207223] BUG: unable to handle kernel NULL pointer dereference at 0000000000000018
[ 4605.210789] IP: [<ffffffffa07b5635>] ieee80211_parse_bitrates+0x65/0x110 [mac80211]
The splat was preceeded by WARN_ON(!chanctx_conf)
in ieee80211_get_sdata_band().

mac80211: fix WPA with VLAN on AP side with ps-sta again
commit de74a1d9032f4d37ea453ad2a647e1aff4cd2591
"mac80211: fix WPA with VLAN on AP side with ps-sta"
fixed an issue where queued multicast packets would
be sent out encrypted with the key of an other bss.
commit "7cbf9d017dbb5e3276de7d527925d42d4c11e732"
"mac80211: fix oops on mesh PS broadcast forwarding"
essentially reverted it, because vif.type cannot be AP_VLAN
due to the check to vif.type in ieee80211_get_buffered_bc before.
As the later commit intended to fix the MESH case, fix it
by checking for IFTYPE_AP instead of IFTYPE_AP_VLAN.

cfg80211: remove racy beacon_interval assignment
In case of AP mode, the beacon interval is already reset to
zero inside cfg80211_stop_ap(), and in the other modes it
isn't relevant. Remove the assignment to remove a potential
race since the assignment isn't properly locked.
