Subject: [PATCH] mac80211: fix station hash table max_size config dependency

From: roynatech2544 <whiteshell2544@...er.com>

Commit ebd82b3 ("mac80211: make station hash table max_size configurable") introduced config
MAC80211_STA_HASH_MAX_SIZE, which is defined unconditionally even if MAC80211 is not set.
It doesn't look like it is dependent of MAC80211_DEBUG_MENU either, as its only user is sta_info.c
which is compiled unconditionally when MAC80211 != n. And without this config set somewhere, compile
would error out.

Make it depend on MAC80211 to correctly hide the config when MAC80211=n
