scsi, pci, qdev, isa-bus, sysbus: don't let *_get_fw_dev_path return NULL
Use g_strdup rather than strdup, because the sole caller
(qdev_get_fw_dev_path_helper) assumes it gets non-NULL, and dereferences
it. Besides, in that caller, the allocated buffer is already freed with
g_free, so it's better to allocate with a matching g_strdup.
In one case, (scsi-bus.c) it was trivial, so I replaced an snprintf+
g_strdup combination with an equivalent g_strdup_printf use.
