lib/nvmf: Factor out abort operation on the specific qpair into a function

Factor out abort operation on the specific qpair into a helper
function nvmf_qpair_abort_request().

After this refactoring, nvmf_ctrlr_abort_done() calls
_nvmf_request_complete() only if the passed status is zero.
If the passed status is not zero, nvmf_qpair_abort() is responsible
for calling _nvmf_request_complete() instead.
