IB/qib: add missing braces in do_qib_user_sdma_queue_create()

Commit c804f07 moved qib_assign_ctxt() to
do_qib_user_sdma_queue_create() but dropped the braces
around the statements.

This was spotted by coccicheck (coccinelle/spatch):

$ make C=2 CHECK=scripts/coccicheck drivers/infiniband/hw/qib/

drivers/infiniband/hw/qib/qib_file_ops.c:1583:2-23: code aligned with following code on line 1587

This patch adds braces back.
