Ryder LeeandFelix Fietkau 9f60dd01e6 wifi: mt76: mt7996: 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.
