qcacld-3.0: Do LRO enable and disable on iface up and down

In case of dynamic mode driver load/unload, a timer is started
whenever driver is loaded. If some iface don't come up in certain
amount of time, this timer expires resulting in cleanup of hif_softc
structure. This structure has LRO flush callback stored in it which
also gets removed as part of cleanup. As this callback is stored only
at the time of driver load, this cause a break in LRO functionality
and also an assert in HOST driver as driver is trying to remove the
callback at the time of driver unload which has already been removed
at the time of timer expiration.

Do LRO enable and disable at the time of ifconfig up and ifconfig
down. This ensures that even after the modules are cleaned when
timer expires, the callback is registered again at the time of
ifconfig up.
