[PATCH] fat: fix mtime handing in __fat_write_inode

[Jeff Layton <jlayton@kernel.org>]

Klara reported seeing mangled mtimes when dealing with FAT. Fix the
braino in the FAT conversion to the new timestamp accessors.

Fixes: e57260ae3226 (fat: convert to new timestamp accessors)

This patch fixes the bug that Klara reported late yesterday. The issue
is a bad by-hand conversion of __fat_write_inode to the new timestamp
accessor functions.

Christian, this patch should probably be squashed into e57260ae3226.

Thanks!
Jeff
