[PATCH v3 13/16] console: unconditionally run resched() in ctrlc()

[Ahmad Fatoum]

From: Ahmad Fatoum <ahmad at a3f.at>

ctrlc is allowed only after init and reboot mode scripts have run, so
these scripts run uninterruptible. A side effect of this is that all
calls to ctrlc() will immediately return with false without running the
pollers. While init scripts shouldn't run too long, it's still
surprising behavior. Thus call resched() first thing in ctrlc().
