qcacld-3.0: Prevent roaming latency caused by LL stat ops
qcacld-2.0 to qcacld-3.0 propagation
Framework may initiate LL stat ops while roaming is
in middle, which in turn block the call or wait for
timeout hence introducing roaming delay.
This delay can be overcome by avoiding LL stat ops
if it is triggered in between the roaming.
