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.
