[PATCH] fs/fat: Initialize local variable finfo

[franck.jullien at gmail.com]

From: Franck Jullien <franck.jullien at gmail.com>

fat_stat in fs/fat.c declares finfo but doesn't initialize it.
When get_fileinfo is called, fno->lfname and fno->lfsize are
tested but haven't been zeroed...This can lead to a wrong
behavior.
