qcacld-3.0: Update fils erp sequence number after roaming

Fils info is stored per vdev. In RSO scan mode command, in FILS
TLV, the next ERP sequence number to be used in the next FILS
connection is sent to firmware and is filled from the vdev fils
info. But after roam sych event is received, the erp sequence
number is not updated in the vdev fils info, causing FILS roaming
failure.

Update the fils erp sequence number to vdev fils info after
roaming.
