[PATCH 1/2] RDMA/hfi1: Fix error return code in parse_platform_config()

[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: 97167e813415 ("staging/rdma/hfi1: Tune for unknown channel if configuration file is absent")
