usb: wusbcore: fix kernel panic on HWA unplug
This patch adds ref counting to sections of code that operate on struct
wa_xfer objects that were missing it. Specifically, error handling
cases need to be protected from freeing the xfer while it is still in
use elsewhere. This fixes a kernel panic that can occur when pulling
the HWA dongle while data is being transferred to a wireless device.
