ath10k: Fix the tx stats bytes & packets parsing

In tx_stats debugfs, txrate->flags may contain multiple bits. For
example, RATE_INFO_FLAGS_SHORT_GI could be set, and tx stats bytes
and packets will be not updated correctly.

Fix this issue by using bit operation to check txrate->flags.

Tested HW: QCA9984
