qcacld-3.0: Add INI param to ignore HT op mode of peer AP

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

Currently even if peer AP is in Legacy mode, driver can enable
11g protection, even though there is no 11g AP in vicinity.

As a part of fix, add an INI param which will enable 11g
protection only when there is a 11g AP in vicinity.
