sched: Only call post_select() if task is not in error state.

Fixes a bug introduced in 86611501 which caused para_audiod to segfault
if the connection to para_server terminated unexpectedly.

para_audiod relies (in kill_btrn()) on a task's ->post_select method
never being called if t->error is negative.
