[PATCH 1/9] RDMA/hfi2: Propagate sdma_txinit_ahg() errors in user_sdma.c

Propagate errors from sdma_txinit_ahg() in set_txreq_header_ahg()
rather than implicitly ignoring them and continuing. This matches the
fix applied to hfi1 in commit 091c6162c022 ("RDMA/hfi1: Propagate
sdma_txinit_ahg() errors").
