qcacld-3.0: Select transmit power as per 11.7.6 IEEE Section

Browse Source 
Currently, if power constraint is advertised by AP then local
max tx power is calculated as per the rule defined in 9.4.2.13
(Power Constraint element) i.e regulatory power - local constraint
advertised by AP. As per the rule defined in 11.7.6
(Transmit power selection) transmit power for STA should be less
than or equal to the minimum of the local maximum transmit power
level and regulatory client maximum power.

Fix is instead of populating max_tx_power as diff of regulatory power
and derived local max tx power, populate max_tx_power to the MIN
of regulatory power and local max tx power to align with IEEE
standard.
