[PATCH 5.4 053/108] bnxt_en: Add missing check for BNXT_STATE_ABORT_ERR in bnxt_fw_rset_task()

[ Upstream commit 6cd657cb3ee6f4de57e635b126ffbe0e51d00f1a ]

In the BNXT_FW_RESET_STATE_POLL_VF state in bnxt_fw_reset_task() after all
VFs have unregistered, we need to check for BNXT_STATE_ABORT_ERR after
we acquire the rtnl_lock. If the flag is set, we need to abort.

Fixes: 230d1f0de754 ("bnxt_en: Handle firmware reset.")
