vfio/{iommufd,container}: Remove caps::aw_bits

Browse source 
Remove caps::aw_bits which requires the bcontainer::iova_ranges being
initialized after device is actually attached. Instead defer that to
.get_cap() and call vfio_device_get_aw_bits() directly.

This is in preparation for HostIOMMUDevice::realize() being called early
during attach_device().
