This should be checked to ensure the ubifs_assert is working as
intended, I've done the suggested annotation in this patch.

This looks like a bugfix as your tmp was a u32 so there was truncation in
the atime, mtime, ctime value, probably not intentional, add a tmp_le64
and use it here.

Do byteshifting at compile time of the flag value. Annotate the saved_flags
as le32.

fs/ubifs/debug.c:368:10: warning: cast from restricted __le64
Should be checked if the truncation was intentional, I've changed the
printk to print the full width.
