wifi: ath12k: eliminate redundant debug mask check in ath12k_dbg()

The current implementation includes a debug mask check both in the macro
expansion and in the function __ath12k_dbg(), which is unnecessary.

Simplify the code by removing the redundant check from the helper function
__ath12k_dbg().

While at this, rename the first argument in macro from ar to ab since the
first argument name in the function __ath12k_dbg() is ab.
