net/qede: fix VF reload

On ungraceful termination of DPDK application, PMD VF driver
fails to re-load due to PF seeing the VF in unexpected state
during VF acquisition handshake.

This patch fixes it by allowing VF to request the PF for soft
FLR during the load in such cases so that it can get cleanly
re-loaded.
