qemu: rename virDomainDeviceInfoPtr variables to avoid confusion

The virDomainDeviceInfoPtrs in qemuCollectPCIAddress and
qemuComparePCIDevice are named "dev" and "dev1", but those functions
will be changed (in order to match a change in the args sent to
virDomainDeviceInfoIterate() callback args) to contain a
virDomainDeviceDefPtr device.

This patch renames "dev" to "info" (and "dev[n]" to "info[n]") to
avoid later confusion.
