wifi: libertas: notify firmware load wait on disconnect
Currently, when the firmware is not fully loaded and if_usb_disconnect
is called, if_usb_prog_firmware gets stuck waiting for
cardp->surprise_removed or cardp->fwdnldover while lbs_remove_card
also waits for the firmware loading to be completed, which never happens.
This caused the reported syzbot bug. To address this, the wake_up
function call can be added in the if_usb_disconnect function which notifies
the if_usb_prog_firmware thread and resolves the firmware loading.
Fixes: 954ee164f4f4 ("[PATCH] libertas: reorganize and simplify init sequence")
