nfs[23] tcp breakage in mount with binary options
We forget to set nfs_server.protocol in tcp case when old-style binary
options are passed to mount. The thing remains zero and never validated
afterwards. As the result, we hit BUG in fs/nfs/client.c:588.
Breakage has been introduced in NFS: Add nfs_alloc_parsed_mount_data
merged yesterday...
