[PATCH v5 wireless-next 07/12] wifi: cfg80211: allow ToDS=0/FromDS=0 data frames on NAN data interfaces

[Miri Korenblit <miriam.rachel.korenblit@intel.com>]

From: Daniel Gabay <daniel.gabay@intel.com>

According to Wi-Fi Aware (TM) specification Table 3, data frame should
have 0 in the FromDS/ToDS fields. Don't drop received frames with 0
FromDS/ToDS if they are received on NAN_DATA interface.
While at it, fix a double indent.
