exfat: properly set s_time_gran
The s_time_gran superblock field indicates the on-disk nanosecond granularity of timestamps, and for exfat that seems to be 10ms, so set s_time_gran to 10000000ns. Without this, in-memory timestamps change when they get re-read from disk. Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com>
