[PATCH 03/10] rtlwifi: Add sta_statistics of mac80211's op, and set filled=0 by default

[<pkshih@realtek.com>]

From: Ping-Ke Shih <pkshih@realtek.com>

When using iwconfig to check wifi status, wext uses 'static struct' of
sinfo to get station info so sinfo->filled will be persistent. Since the
commit 2b9a7e1bac24 ("mac80211: allow drivers to provide most station
statistics") assumes driver initializes sinfo->filled to declare supported
fields, without initialization it will report wrong info. This commit
simply set 'filled' to be zero simply, and left sinfo to be filled by
mac80211.
