xfrm: provide message size for XFRM_MSG_MAPPING 



The compat 64=>32 translation path handles XFRM_MSG_MAPPING, but
xfrm_msg_min[] does not provide the native payload size for this
message type.

Add the missing XFRM_MSG_MAPPING entry so compat translation can size
and translate mapping notifications correctly.

Fixes: 5461fc0c ("xfrm/compat: Add 64=>32-bit messages translator")
