bnxt_en: Improve device shutdown method.
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: c20dc142 ("bnxt_en: Disable bus master during PCI shutdown and driver unload.")
