Subject: [PATCH -next] ocfs2: remove set but not used variable 'end'

Fixes gcc '-Wunused-but-set-variable' warning:

fs/ocfs2/file.c: In function 'ocfs2_prepare_inode_for_write':
fs/ocfs2/file.c:2143:9: warning:
 variable 'end' set but not used [-Wunused-but-set-variable]

It not used any more after commit
