qcacld-3.0: Fix wrong subnet_change_status derivation after roam

Subnet change status field is obtained from bits 4 & 5 of the
roam_reason field in roam synch indication. But in
cm_fill_roam_info() the subnet_change_status is received from
the masked roam reason field and is always 0. So after
roaming to AP with different subnet wrong subnet change
indication is sent to userspace and ultimately NUD failure is
triggered.

Get the subnet_change_status directly from the roam synch
indication
