Btrfs: Remove unused variable 'last_index' in file.c
The variable 'last_index' is calculated in the __btrfs_buffered_write function and passed as a parameter to the prepare_pages function, but is not used anywhere in the prepare_pages function. Remove instances of 'last_index' in these functions. Signed-off-by: Mitch Harder <mitch.harder@sabayonlinux.org> Signed-off-by: Chris Mason <chris.mason@oracle.com>
