[ Upstream commit 5567ae4a8d569d996d0d88d0eceb76205e4c7ce5 ]
Especially when bnxt_shutdown() is called during kexec, we need to disable MSIX and disable Bus Master to completely quiesce the device. Make these 2 calls unconditionally in the shutdown method.
Fixes: c20dc142dd7b ("bnxt_en: Disable bus master during PCI shutdown and driver unload.")
