xfrm_user: fix return value from xfrm_user_rcv_msg



commit 83e2d0587ae859aae75fd9d246c409b10a6bd137 upstream.

It doesn't support to run 32bit 'ip' to set xfrm objdect on 64bit host.
But the return value is unknown for user program:

ip xfrm policy list
RTNETLINK answers: Unknown error 524

Replace ENOTSUPP with EOPNOTSUPP:

ip xfrm policy list
RTNETLINK answers: Operation not supported
