smtp.c: Fixed an issue with the EOB checking

Curl_smtp_escape_eob() would leave off final CRLFs from emails ending
in multiple blank lines additionally leaving the smtpc->eob variable
with the character count in, which would cause problems for additional
emails when sent through multiple calls to curl_easy_perform() after a
CURLOPT_CONNECT_ONLY.
