wifi: rt2x00: restart beacon queue when hardware reset

mainline inclusion
from mainline-v6.8-rc1
commit a11d965a218f0cd95b13fe44d0bcd8a20ce134a8
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I96GO9
CVE: CVE-2023-52595

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a11d965a218f



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

When a hardware reset is triggered, all registers are reset, so all
queues are forced to stop in hardware interface. However, mac80211
will not automatically stop the queue. If we don't manually stop the
beacon queue, the queue will be deadlocked and unable to start again.
This patch fixes the issue where Apple devices cannot connect to the
AP after calling ieee80211_restart_hw().
