gstpad: Fix flush-stop event handling

Browse source 
A flush-stop event would make a pad unflushing, causing it
to start acting as an activated pad. This, for example,
could lead to the chain function being called when stuff
isn't initialized.

This could happend when setting qtdemux to NULL while a seek
was being handled in the upstream filesrc (in push mode).

This patch makes it check if it is activated before setting
it to unflushing.
