fuse: minor improvements for readdir(plus)
Instead of using 'int' for the sizes, use a 'size_t' as it is more correct. Save the size of a fuse_dirent in a temporary variable so that strlen() on the filename is called fewer times. Also correcting some typos in comments. Change-Id: Ic62d9d729a86a1a6a53ed1354fce153bac01d860 BUG: 1074023 Reported-by: Kaleb S.
