bnxt_en: Fix the PCI-AER routines
We do not support two simultaneous recoveries so check for reset flag, BNXT_STATE_IN_FW_RESET, and do not proceed with AER further. When the pci channel state is pci_channel_io_frozen, the PCIe link can not be trusted so we disable the traffic immediately and stop BAR access by calling bnxt_fw_fatal_close(). BAR access after AER fatal error can cause an NMI. Fixes: f75d9a0a ("bnxt_en: Re-write PCI BARs after PCI fatal error.") Signed-off-by:Vikas Gupta <vikas.gupta@broadcom.com> Signed-off-by:
