io: make qio_channel_command_new_pid() static
The function isn't used outside of qio_channel_command_new_spawn(), which is !win32-specific. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

+ * @readfd: the FD connected to the command's stdout
+ * @pid: the PID of the running child command
+ * @errp: pointer to a NULL-initialized error object
+ *
+ * Create a channel for performing I/O with the
+ * previously spawned command identified by @pid.
+ * The two file descriptors provide the connection
+ * to command's stdio streams, either one or which
+ * may be -1 to indicate that stream is not open.

+ * The channel will take ownership of the process

+ * Similarly it will take responsibility for
+ * closing the file descriptors @writefd and @readfd.
+ *
+ * Returns: the command channel object, or NULL on error
