nfs4_proc_unlk() acquires the nfs_open_context from the file_lock's fl_file->private, but we will not always have a referenced fl_file in this path. Instead, pass along the nfs_open_context from the call to nfs4_proc_lock(). This allows us to use nfs4_proc_unlck() without a valid reference in fl_file.
