Ryder LeeandFelix Fietkau ee2bb33372 wifi: mt76: mt7921: fix potential tx_retries underflow 
When FIELD_GET returns 0 for the retry count, subtracting 1 causes
an unsigned integer underflow, resulting in tx_retries becoming a
very large value (0xFFFFFFFF for u32).

Fix by checking if count is non-zero before subtracting 1.

Fixes: 9aecfa754c7f ("wifi: mt76: mt7921e: report tx retries/failed counts in tx free event")
