[libvirt] [PATCH 1/4] virsh-domain: use correct base for virStrToLong_ui

While parsing device addresses we should use correct base and don't
count on auto-detect.  For example, PCI address uses hex numbers, but
each number starting with 0 will be auto-detected as octal number and
that's wrong.  Another wrong use-case is for PCI address if for example
bus is 10, than it's incorrectly parsed as decimal number.

PCI and CCW addresses have all values as hex numbers, IDE and SCSI
addresses are in decimal numbers.
