Subject: [PATCH net-next 3/7] bnxt_en: Remove the redundant BNXT_EN_FLAG_MSIX_REQUESTED flag

From: Kalesh AP <kalesh-anakkur.purayil@...adcom.com>

MSIX is always requested when the RoCE driver calls bnxt_register_dev().
We already check bnxt_ulp_registered(), so checking the flag is
redundant.  It was a left-over flag after converting to auxbus, so
remove it.
