bnxt_alloc_ctx_mem() calls bnxt_hwrm_func_backing_store_qcaps() to
allocate the memory for bp->ctx.  Initialize bp->ctx with the allocated
memory and let the caller free it during unwind.  The unwind logic is
already there, we just need to always set bp->ctx to the allocated
memory so the caller will always free it.  This simplifies the logic
and makes it easier to expand on the backing store logic.
