ext4: minor fix for ext4_split_extent_zeroout()

We missed storing the error which triggerd smatch warning:

	fs/ext4/extents.c:3369 ext4_split_extent_zeroout()
	warn: duplicate zero check 'err' (previous on line 3363)

fs/ext4/extents.c
    3361
    3362         err = ext4_ext_get_access(handle, inode, path + depth);
    3363         if (err)
    3364                 return err;
    3365
    3366         ext4_ext_mark_initialized(ex);
    3367
    3368         ext4_ext_dirty(handle, inode, path + depth);
--> 3369         if (err)
    3370                 return err;
    3371
    3372         return 0;
    3373 }

Fix it by correctly storing the err value from ext4_ext_dirty().
