[PATCH v3] cfg80211: avoid restoring the regulatory during disconnect

[Rajkumar Manoharan <rmanohar@qti.qualcomm.com>]

From: Sachin Ahuja <sahuja@codeaurora.org>

When STA disconnects, cfg80211 restores the regulatory setting
to world domain. For the drivers that ignore country ie, cfg80211
should remain in the default country code which is configured
at driver load and should do not be restored to world reg domain.
