The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).

Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.

Note: The following patch series only does some code clean up.
The previous versions mentioned a bug fix but it appears as a mix up
with some local changes because NL80211_STA_INFO_TID_STATS value actually
equals 31.

Changes in v3:
  - Better phrasing commit messages due to the above note
  - Align patches to latest mac80211-next
