Namjae Jeon 7a3bbbadac ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16() ...

commit d10c77873ba1e9e6b91905018e29e196fd5f863d upstream.

If ->NameOffset/Length is bigger than ->CreateContextsOffset/Length,
ksmbd_check_message doesn't validate request buffer it correctly.
So slab-out-of-bounds warning from calling smb_strndup_from_utf16()
in smb2_open() could happen. If ->NameLength is non-zero, Set the larger
of the two sums (Name and CreateContext size) as the offset and length of
the data area.
