staging: rtl8712: Fix some tests against some 'data' subtype frames
Commit 6e2baa44c6d1 ("staging: rtl8712: remove enum WIFI_FRAME_SUBTYPE")
was wrong because:
WIFI_DATA_NULL != IEEE80211_STYPE_NULLFUNC
WIFI_DATA_CFACK != IEEE80211_STYPE_DATA_CFACK
WIFI_DATA_CFPOLL != IEEE80211_STYPE_DATA_CFPOLL
WIFI_DATA_CFACKPOLL != IEEE80211_STYPE_DATA_CFACKPOLL
the WIFI_DATA_xxx definitions include WIFI_DATA_TYPE, which is 'BIT(3)'.
Restore the previous behavior by adding the missing
'IEEE80211_FTYPE_DATA |' (0x0008, that is to say BIT(3)) when these values
are used.
Hopefully, the wrong commit was small enough and hand review is possible.
