[PATCH] Correctly deal with events in the past in calc_next_timeout

[maximlevitsky@xxxxxxxxx (Maxim Levitsky)]

Correctly deal with events in the past in calc_next_timeout
This fixes a gstreamer mixer regression, when it can't control the volume,
after few changes.

From: Maxim Levitsky <maximlevitsky@xxxxxxxxx>

pa_usec_t is unsigned, thus it will always be >= 0
This makes gstreamer pulse mixer work again
