bnxt_en: fix the handling of PCIE-AER
Fix the sequence required for PCIE-AER. While slot reset occurs, firmware
might not be ready and the driver needs to check for its recovery. We
also need to remap the health registers for some chips and clear the
resource reservations. The resources will be allocated again during
bnxt_io_resume().
Fixes: fb1e6e562b37 ("bnxt_en: Fix AER recovery.")
