qcacmn: Confirm HP register init when enabling IPA pipes

Browse Source 
As a part of enabling IPA pipes, the WBM2SW2 head
pointer register is written with the number of
buffers which have been allocated initially. This
register write is a critical one and failure in
writing this register can be fatal.

Confirm the written value, when initializing
the HP register for WBM2SW2 (for IPA).
