qcacld-3.0: Update deficient_desc when the TX pool is replenished

It's needed to update deficient_desc count when the deficient pools
are replenished, otherwise, when there are multiple interfaces and
do intetfaces on/off stress test, it's possible some interfaces will
run out of system tx pool descriptors when do ol_tx_flow_pool_resize,
and other interface can't get any available tx descriptors.
