RDMA/uverbs: Push out CQ buffer umem processing into a helper
Extract the UVERBS_ATTR_CREATE_CQ_BUFFER_* parser from the CQ
create handler into uverbs_create_cq_get_buffer_desc(), and wrap
it in ib_umem_get_cq_tmp(), the umem-producing helper the cq_create
handler now calls.
ib_umem_get_cq_tmp() is temporary; subsequent patches replace it
with driver-owned ib_umem_get_cq_buf*() wrappers built on the
same parser, and remove it once all CQ drivers have switched.
