[PATCH ath-next 2/6] wifi: ath10k: usb: set soft_unbind

[Tomas Paukrt]

The USB core disables the endpoints of an interface before it calls the
disconnect callback, unless the driver sets soft_unbind. ath10k still
sends WMI commands at that time, because mac80211 removes the interfaces
during the unregistration, and these commands fail when the driver is
unloaded:

  usb 1-1.1: failed to delete WMI vdev 0: -22
  usb 1-1.1: could not suspend target (-22)

Set soft_unbind to keep the endpoints enabled until the disconnect
callback returns.

Tested-on: QCA9377 hw1.1 USB 0.0.0.111
