OGAWA Hirofumi 35033ab988 fat: fix memory allocation failure handling of match_strdup()

In parse_options(), if match_strdup() failed, parse_options() leaves
opts->iocharset in unexpected state (i.e.  still pointing the freed
string).  And this can be the cause of double free.

To fix, this initialize opts->iocharset always when freeing.
