exfat: fix setting uninitialized time to ctime/atime

An uninitialized time is set to ctime/atime in __exfat_write_inode().
It causes xfstests generic/003 and generic/192 to fail.

And since there will be a time gap between setting ctime/atime to
the inode and writing back the inode, so ctime/atime should not be
set again when writing back the inode.
