issue of smtpmail-via-smtp

[Binjo <binjo.cn@gmail.com>]

hi,

i'm using the latest no gnus and gnu emacs 24 under windows, with gnutls
enabled. the following changes allows me to send mail as usual, it turns out
`network-stream-get-response' will wait for the ":end-of-command" infinitly,
when searching for "^[0-9]+ .*\r\n". should there be a timeout check?

this change just works for me, i'm no expert of gnus/smtpmail protocol, so
please verify this, thanks.
