qcacmn: Fix calculation of getting head/tail pointer

Browse Source 
The current calculation of head/tail pointer for
srng gives an index in the array by skipping
entry_size dwords.
The head/tail pointers are preffered to be the
index values like in the srng registers, which
brings them in alignment with the other usage of
head/tail pointers.

Fix the calculation of head/tail pointers for srng
by avoiding the division by srng entry size.
