qcacmn: Add dequeue value in delayed register write entry

The delayed register write for srngs will have
the value of the HP/TP at the time of enqueue,
but the final value which is written to the
hp_addr/tp_addr will be determined based on
HP/TP value at the time of dequeue of the
entry for a particular srng.

Hence to know what was the exact value which
was written to the HP/TP address, add one more
element in the delayed register write entry.
This element will contain the value of the
HP/TP which was actually written to the address.
