Robbie Harwood e43f3d93b2 fs/fat: Don't error when mtime is 0 
In the wild, we occasionally see valid ESPs where some file modification
times are 0. For instance:

    5 directories, 17 files

This causes grub-probe failure, which in turn causes grub-mkconfig
failure. They are valid filesystems that appear intact, and the Linux
FAT stack is able to mount and manipulate them without complaint.

The check for mtime of 0 has been present since
20def1a3c3952982395cd7c3ea7e78638527962b (fat: support file
modification times).
