wifi: mwifiex: send world regulatory domain to driver

Browse Source 
[ Upstream commit 56819d00bc2ebaa6308913c28680da5d896852b8 ]

The world regulatory domain is a restrictive subset of channel
configurations which allows legal operation of the adapter all over the
world. Changing to this domain should not be prevented.

Fixes: dd4a9ac05c ("mwifiex: send regulatory domain info to firmware only if alpha2 changed") changed
