genirq/irq_sim: Initialize work context pointers properly

Browse Source 
[ Upstream commit 8a2277a3c9 ]

Initialize `ops` member's pointers properly by using kzalloc() instead of
kmalloc() when allocating the simulation work context. Otherwise the
pointers contain random content leading to invalid dereferencing.
