mm/swapfile.c: remove the incorrect code comment

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 EINVAL' is obsolete.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.
