xen-pciback: Fix pcistub_device ref leak in pcistub_get_gsi_from_sbdf()
pcistub_get_gsi_from_sbdf() obtains the stub device with
pcistub_device_find(), which returns it with its kref incremented, and
returns psdev->gsi without dropping that reference again. The caller
cannot release it either, so every lookup leaks one reference to the
stub device.
Release the reference after reading gsi.
Fixes: 2fae6bb7be32 ("xen/privcmd: Add new syscall to get gsi from dev")
