bus/cdx: fix release in probing for secondary process

The variable cdx_addr is a stack-allocated zero-initialized char array, but
it is never used anywhere except in an error handler to stand it as a
device bus address for a VFIO device release call. This is incorrect, as it
should have been actual device address, so fix the code to reflect that.
