qcacmn: fix REO2SW ring full issue

Browse source 
When reap data from REO2SW ring and if the TP catches up to cached
HP, current logic will update HP again and give a second chance to
reap data. but the TP is not updated to ring register, if more data
is received on this ring then HP easily catches up to TP and the ring
is full.
Update TP as well if HP get chance be updated.
