mctp: return -ENOPROTOOPT for unknown getsockopt options
[ Upstream commit a125c8fb9ddbcb0602103a50727a476fd30dec01 ]
In mctp_getsockopt(), unrecognized options currently return -EINVAL.
In contrast, mctp_setsockopt() returns -ENOPROTOOPT for unknown
options.
Update mctp_getsockopt() to also return -ENOPROTOOPT for unknown
options. This aligns the behavior of getsockopt() and setsockopt(),
and matches the standard kernel socket API convention for handling
unsupported options.
