RDMA/core: Consolidate ib_create_srq flows

Browse Source 
The uverbs layer largely duplicate the code in ib_create_srq(), with the
slight difference that it passes in a udata. Move all the code together
into ib_create_srq_user() and provide an inline for kernel users, similar
to other create calls.
