Revert changes to return errors when sending commands, getenv or getret
This fixes software which did not expect to receive an error after sending
specific commands. Sending "go" for instance returned a connection reset
error which was interpreted as "could not send command" while this behavior
is completely correct. This also fixes idevicerestore's "Unable to send iBEC"
problems.
