drivers: staging: rtl8723bs: Fix locking in rtw_scan_timeout_handler()
Commit cc7ad0d77b51 ("drivers: staging: rtl8723bs: Fix deadlock in
rtw_surveydone_event_callback()") besides fixing the deadlock also
modified rtw_scan_timeout_handler() to use spin_[un]lock_irq()
instead of spin_[un]lock_bh().
Disabling the IRQs is not necessary since all code taking this lock
runs from either user contexts or from softirqs
rtw_scan_timeout_handler() is the only function taking pmlmepriv->lock
which uses spin_[un]lock_irq() for this. Switch back to
spin_[un]lock_bh() to make it consistent with the rest of the code.
