qcacmn: Support multiple TX rings in DP interrupt handler

Browse Source 
In dp_service_srngs, the current logic assumes that WBM2SWRELEASE ring
number as obtained from interrupt_ctx->tx_mask matches the index of
soc->tx_comp[] array. However this may not be true, esp for HMT.
Add logic to fix the same.

Use a separate macro to enable use of single TX ring.
