HID: asus: use spinlock to safely schedule workers

mainline inclusion
from mainline-v6.2
commit 4ab3a086
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6I7U9
CVE: CVE-2023-1079

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4ab3a086d10eeec1424f2e8a968827a6336203df



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

Use spinlocks to deal with workers introducing a wrapper
asus_schedule_work(), and several spinlock checks.
Otherwise, asus_kbd_backlight_set() may schedule led->work after the
structure has been freed, causing a use-after-free.
