sma: fix multiple bus support for NVMe/vfio_user plugin

Browse Source 
In original code, device search was performed only on first
attached bus. If device resided on second attached bus, it couldn't
be found and properly deleted in qemu.

This patch allows to traverse all attached buses to find required
device.
