Alok Tiwari 2f08df544a mctp: return -ENOPROTOOPT for unknown getsockopt options 
[ Upstream commit a125c8fb9d ]

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.
