wifi: carl9170: rx: track PHY errors via debugfs

Browse source

Count PHY errors reported by the hardware in the RX status and
expose the counter through debugfs as rx_phy_errors.  Previously,
PHY errors from ar9170_rx_phystatus were silently ignored (marked
with a TODO comment).

The counter helps diagnose RF environment issues (interference,
multipath, low SNR) without requiring monitor mode or additional
tooling.
