Subject: bnxt_en: Improve AER slot reset.
From: Michael Chan <michael.chan@xxxxxxxxxxxx>
[ Upstream commit bae361c54fb6ac6eba3b4762f49ce14beb73ef13 ]
Improve the slot reset sequence by disabling the device to prevent bad
DMAs if slot reset fails. Return the proper result instead of always
PCI_ERS_RESULT_RECOVERED to the caller.
Fixes: 6316ea6db93d ("bnxt_en: Enable AER support.")
