isdn/eicon: don't call flush_scheduled_work() from diva_os_remove_soft_isr()
isdn/eicon: don't call flush_scheduled_work() from diva_os_remove_soft_isr()

diva doesn't use workqueue and there is no reason to flush the system
workqueue from diva_os_remove_soft_isr().  Remove it.

This is to prepare for the deprecation and removal of
flush_scheduled_work().
