net: Fix the devmem sock opts and msgs for parisc

The devmem socket options and socket control message definitions
introduced in the TCP devmem series[1] incorrectly continued the socket
definitions for arch/parisc.

The UAPI change seems safe as there are currently no drivers that
declare support for devmem TCP RX via PP_FLAG_ALLOW_UNREADABLE_NETMEM.
Hence, fixing this UAPI should be safe.

Fix the devmem socket options and socket control message definitions to
reflect the series followed by arch/parisc.
