[PATCH AUTOSEL 5.5 58/66] bnxt_en: Improve device shutdown method.

[Sasha Levin]

From: Vasundhara Volam <vasundhara-v.volam@xxxxxxxxxxxx>

[ 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.")
