[PATCH 1/2] tools/ctrl: Silence missing GSI in xc_pcidev_get_gsi()

[Jason Andryuk]

It is valid for a PCI device to not have a legacy IRQ.  In that case, do
not print an error to keep the lgs clean.

This relies on pciback being updated to return -ENOENT for a missing
GSI.

Fixes: b93e5981d258 ("tools: Add new function to get gsi from dev")
