QProcess/Unix: do not toggle a state of the write notifier twice
_q_canWrite() unconditionally disabled the write notifier before the
writing, and might have enabled it again afterwards. This caused
unnecessary processing in the event dispatcher and could result in
extra system calls.
Actually setting the state at the moment when the write buffer size
is determined is enough.
