RDMA/srp: Fix error return code in srp_parse_options()
[ Upstream commit
ed461b30b22c8fa85c25189c14cb89f29595cd14 ]
In the previous iteration of the while loop, the "ret" may have been
assigned a value of 0, so the error return code -EINVAL may have been
incorrectly set to 0. To fix set valid return code before calling to
goto. Also investigate each case separately as Andy suggessted.
