Since commit eb085574a752 ("mm, swap: fix race between swapoff and
some swap operations"), the non_swap_entry() checking has been taken
off from function __swap_duplicate(). Hence, in the kernel-doc comment,
the line 'swp_entry is migration entry -> EINVAL' is obsolete. Remove
that line to avoid misleading people.
