net: Cap number of elements for sendmmsg
To limit the amount of time we can spend in sendmmsg, cap the number of elements to UIO_MAXIOV (currently 1024). For error handling an application using sendmmsg needs to retry at the first unsent message, so capping is simpler and requires less application logic than returning EINVAL.
