libsigrok: demo: close pipes on dev_acquisition_stop()

Fixes a bug where new acquisition failes due to leftover pipes from
previous acquisitions:
	sr: demo: dev_acquisition_start: pipe() failed
Indeed, PulseView had 2024 pipes opened. With this fix, it stabilizes at
33 with sampling thread active.
