read_fd_message: distinguish prints of log message 



When VM shutdown there will be an error message 'VHOST_CONFIG: recvmsg failed' printed.
The return value of recvmsg will be 0 when the peer has performed an orderly shutdown,
or -1 if an error occurred. So adding logs to distinguish these two different situations
to avoid confusing and to hint accurately.
