bnxt_en: Reserve rings after PCIe AER recovery if NIC interface is down
After successful PCIe AER recovery, FW will reset all resource
reservations. If it is IF_UP, the driver will call bnxt_open() and
all resources will be reserved again. It it is IF_DOWN, we should
call bnxt_reserve_rings() so that we can reserve resources including
RoCE resources to allow RoCE to resume after AER. Without this
patch, RoCE fails to resume in this IF_DOWN scenario.
Later, if it becomes IF_UP, bnxt_open() will see that resources have
been reserved and will not reserve again.
Fixes: fb1e6e562b37 ("bnxt_en: Fix AER recovery.")
