[PATCH v2] mwifiex: apply radar flag

[Ganapathi Bhat]

From: Karthik Ananthapadmanabha <karthida@marvell.com>

When IEEE80211_CHAN_RADAR is set by cfg80211, passive scan must be
performed. In mwifiex,active scan is performed even though flag is
set from cfg80211. mwifiex_reg_apply_radar_flags() function added
in this patch correctly uses radar flag.
