qemu-char: correct return value from chr_read functions
Even if a CharDriverState's source is blocked by the front-end,
it must not be dropped. The IOWatchPoll that wraps it will take
care of adding and removing it to the main loop. Only remove
the source when the channel is closed; and in that case, make sure
that the wrapping IOWatchPoll is removed too.
These should just be theoretical bugs.
