bnxt_en: Fix TX ring indexing logic

Two spots were missed when modifying the TX ring indexing logic.
The use of unmasked TX index in bnxt_tx_int() will cause unnecessary
__bnxt_tx_int() calls.  The same issue in bnxt_tx_int_xdp() can
result in illegal array index.

Fixes: 6d1add95 ("bnxt_en: Modify TX ring indexing logic.")
