afs: Remove set but not used variables 'before', 'after'
Fixes gcc '-Wunused-but-set-variable' warning:
fs/afs/dir_edit.c: In function afs_set_contig_bits:
fs/afs/dir_edit.c:75:20: warning: variable after set but not used [-Wunused-but-set-variable]
fs/afs/dir_edit.c: In function afs_set_contig_bits:
fs/afs/dir_edit.c:75:12: warning: variable before set but not used [-Wunused-but-set-variable]
fs/afs/dir_edit.c: In function afs_clear_contig_bits:
fs/afs/dir_edit.c:100:20: warning: variable after set but not used [-Wunused-but-set-variable]
fs/afs/dir_edit.c: In function afs_clear_contig_bits:
fs/afs/dir_edit.c:100:12: warning: variable before set but not used [-Wunused-but-set-variable]
They are never used since commit 63a4681ff39c.
Fixes: 63a4681ff39c ("afs: Locally edit directory data for mkdir/create/unlink/...")
