BUG/MINOR: tcp-rules: Stop content rules eval on read error and end-of-input

For now, tcp-request and tcp-response content rules evaluation is
interrupted before the inspect-delay when the channel's buffer is full, the
RX path is blocked or when a shutdown for reads was received. To sum up, the
evaluation is interrupted when no more input data are expected. However, it
is not exhaustive. It also happens when end of input is reached (CF_EOI flag
set) or when a read error occurred (CF_READ_ERROR flag set).

Note that, AFAIK, it is only a problem on HAProy 2.3 and prior when a H1 to
H2 upgrade is performed. On newer versions, it works as expected because the
stream is not created at this stage.

This patch must be backported as far as 2.0.
