wifi: mac80211: fix BSS_CHANGED_UNSOL_BCAST_PROBE_RESP

Browse Source 
[ Upstream commit 816c6bec09 ]

Fix the definition of BSS_CHANGED_UNSOL_BCAST_PROBE_RESP so that
not all higher bits get set, 1<<31 is a signed variable, so when
we do

  u64 changed = BSS_CHANGED_UNSOL_BCAST_PROBE_RESP;

we get sign expansion, so the value is 0xffff'ffff'8000'0000 and
that's clearly not desired. Use BIT_ULL() to make it unsigned as
well as the right type for the change flags.
