reparse.c: Fix big-endian bug when converting file name to lowercase.

When looking up the lowercase equivalent of a Unicode character in
ntfs_fix_file_name, no byte swapping was performed on the ntfschar used
as index into the 'locase' array. This would lead to very strange
results on big-endian systems.
