This removes behaviour, where error code returned from any transport
was always switched to ENOMEM. For example when user tries to send too
big message via SEQPACKET socket, transport layers return EMSGSIZE, but
this error code will be replaced to ENOMEM and returned to user.

Just a minor thing here, I would write
"this error code was always replaced with ENOMEM and returned to user"

To make it clearer that it was the previous behavior.

Anyway, the patch LGTM:
