NFS: Invoke nlmclnt_init during NFS mount processing
Cache an appropriate nlm_host structure in the NFS client's mount point
metadata for later use.
Note that there is no need to set NFS_MOUNT_NONLM in the error case -- if
nfs_start_lockd() returns a non-zero value, its callers ensure that the
mount request fails outright.
