The newly introduced cifs_clone_file_range() function produces
two harmless compile-time warnings:

cifsfs.c: In function 'cifs_clone_file_range':
cifsfs.c:963:1: warning: label 'out_unlock' defined but not used [-Wunused-label]
cifsfs.c:924:20: warning: unused variable 'src_tcon' [-Wunused-variable]

In both cases, removing the extraneous line avoids the warning.
