zsda_nb_pci_devices is incremented when a PCI device is allocated and
decremented when it is released, but the count is never read.
clang 23 reports:
zsda_device.c:10:12: warning: variable 'zsda_nb_pci_devices' set but
not used [-Wunused-but-set-global]
Remove the counter and the three sites that update it.
