NFS: Fix a double unlock from nfs_match,get_client

[ Upstream commit c260121a97a3e4df6536edbc2f26e166eff370ce ]

Now that nfs_match_client drops the nfs_client_lock, we should be
careful
to always return it in the same condition: locked.

Fixes: 950a578c6128 ("NFS: make nfs_match_client killable")
