ath11k_nss: Remove 902-wifi-mac80211-Fix-memory-corruption-during-mesh-beac

We are not targeting 32-bit systems, so this patch is not needed and is
just unnecessary code.

Subject: [PATCH] wifi: mac80211: Fix memory corruption during mesh beacon
update
During mesh beacon update, u64 flag is used to check for
bit set/unset for validation purpose. But, in
'ieee80211_mbss_info_change_notify' API, unsigned long flag
is modified using sizeof(u64). This leads to following issue:
> 'mbss_changed' flag in 'ieee80211_if_mesh' is declared as
unsigned_long which creates an architecture dependency
(32bit vs 64bit) while modifying it with u64 flag which
leads to memory corruption.
Fix above mentioned issue by replacing unsigned long with u64
for changed flag.
