qcacmn: check hal_ring pointer before servicing the ring
Do null check before servicing the ring. When dp_service_srngs()
is common API which gets called when interrupt gets fired for
any ring. Within this API, driver goes one by one to each ring
and service the rings as it is not obvious from interrupt line that
which particular service ring needs to be served.
So race happens when rings are getting initialized and packet has been
arrived to one of the rings. Due to dp_service_srngs() API's
implementation, driver goes to one by one each ring without checking
if all rings are initialized.
