[PATCH 08/14] rtw89: don't flush hci queues and send h2c if power is off

[Ping-Ke Shih <pkshih@realtek.com>]

When disconnecting, it warns somethings after power is off, and we can't
do HCI IO. So, add this patch to avoid below messages:

  rtw89_8852ce 0000:03:00.0: timed out to flush pci txch: 11
  rtw89_8852ce 0000:03:00.0: failed to pre-release fwcmd
