CVE-2022-49954

Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag

In the Linux kernel, the following vulnerability has been resolved:

Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag

syzbot is reporting hung task at __input_unregister_device() [1], for
iforce_close() waiting at wait_event_interruptible() with dev->mutex held
is blocking input_disconnect_device() from __input_unregister_device().

It seems that the cause is simply that commit c2b27ef672992a20 ("Input:
iforce - wait for command completion when closing the device") forgot to
call wake_up() after clear_bit().

Fix this problem by introducing a helper that calls clear_bit() followed
by wake_up_all().
