[PATCH 2/2] RDMA/srp: Fix error return code in srp_parse_options()

[Wang Yufen]

In the previous while loop, "ret" may be assigned zero. Therefore,
"ret" needs to be assigned -EINVAL at the beginning of each loop.

Fixes: e711f968c49c ("IB/srp: replace custom implementation of hex2bin()")
Fixes: 2a174df0c602 ("IB/srp: Use kstrtoull() instead of simple_strtoull()")
Fixes: 19f313438c77 ("IB/srp: Add RDMA/CM support")
