erts: Fix unexpected inet_reply message from failing file:sendfile
A failing file:sendfile call would often send a message
{inet_reply, Port, {error, Reason}} that would pollute the mailbox
of the calling process.
TCP_REQ_SENDFILE has its own reply messages format
{sendfile, _, _} and does not expect an inet_reply message.
Solution: Suppress inet_reply error message if TCP_ADDF_SENDFILE
is set.
