qcacmn: Break from the desc_freelist loop on REO cmd enqueue failure

UPDATE_RX_REO_QUEUE commands are queued in the REO_CMD
ring as part of peer cleanup for each tid. The cb
registered defers pocessing the entries in the
reo_desc_freelist based on either number of pending
entries or time threshold. In the scenario when
these entries from the freelist are processed as part
of next disconnection and if the REO_CMD enqueue fails,
the while loop over reo_desc_freelist does not exit
and will end up in a perpetual loop.

Fix is to break from the desc_freelist loop on REO
cmd enqueue failure.
