[patch 1/3] ib_srpt: fixup error handling in srpt_alloc_ioctx_ring()

[Dan Carpenter <dan.carpenter-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

We returned a freed value instead of NULL on certain error paths.
Complicated error handling generally more error prone, so I've tried
to simplify it a little by removing some gotos.
