qcacld-3.0: Use max tx power allowed to compute link report power

Browse source 
Driver uses max tx power allowed for a particular channel to
calculate link report power and updates max tx power allowed with
calculated link report power. This can result in usage of
MIN_TX_PWR_CAP as max tx power if AP requests power below
MIN_TX_PWR_CAP in link request. Once max tx power reaches
MIN_TX_PWR_CAP, the driver will always use MIN_TX_PWR_CAP in
the link report which could be much less than power allowed for
a particular channel.

Use max tx power allowed for a particular channel always to
compute link report power to fix this issue.
