iwlwifi: do not allow set tx power over channel power limit

When setting tx power in sysfs, check against max channel tx power
limit instead of IWL_TX_POWER_TARGET_POWER_MAX.

Different devices have different max tx power limit; using
IWL_TX_POWER_TARGET_POWER_MAX can excess the limitaion and give wrong
information.
