qcacmn: Cleanup WBUFF code to support additional modules

Browse Source 
Currently, WBUFF logic is being used only for WMI TX buffers and the
logic is closely tied to the WMI TX buffers alone. It is cumbersome
to extend the support of WBUFF for additional modules in the current
state.

Cleanup the WBUFF code and make it generic to add future module
additions.
