----------------------------------------------------------------------

The PF and VF cmdq module resource allocate/free/query APIs are almost the
same espect the suffixes of API names. These same implementations bring
double development and bugfix work.

This patch creates common cmdq resource allocate/free/query APIs called by
PF and VF cmdq init/uninit APIs. The next patch will use the new unified
APIs to replace init/uninit APIs.
