vfio/xe: avoid duplicate reset in xe_vfio_pci_reset_done

xe_vfio_pci_reset_done() sets deferred_reset and, when it manages to
acquire state_mutex itself, hands the cleanup off to
xe_vfio_pci_state_mutex_unlock().

That helper already clears deferred_reset and runs xe_vfio_pci_reset()
before dropping the mutex. Calling xe_vfio_pci_reset() again right
afterwards repeats the reset handling unnecessarily.
