qcacld-3.0: Validate and Update invalid dot11 mode based on band

Browse source 
Currently during get_ch_info dot11 mode is fetched from mlme_cfg
and used to calculate phy mode without any band validation which
may cause errorneous behaviour in below cases due to invalid band
and dot11 mode combination:

a.) Band 2g and dot11 mode 11a
b.) Band 5g and dot11 mode 11g
c.) Band 5g and dot11 mode 11g_only
c.) Band 5g and dot11 mode 11b

Fix is to update modes in case mlme_cfg mode and frequency combination
is invalid.
