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

mainline inclusion
from mainline-v6.0-rc1
commit 3099fc9c
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6DRLU
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3099fc9c2b3a



----------------------------------------------------------------------

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.
