crypto: hisilicon/qm - move alloc qm->wq to qm.c

Before stopping the function, the driver needs to flush all the remaining
work about event irq. Therefore, accelerator drivers use a private
workqueue(qm->wq) to handle event irq instead of the system workqueue.
This patch moves alloc workqueue from sec_main.c and zip_main.c to qm.c.
