Coverity spots subj in following guest triggered code path
pci_write(, data = 0) -> acpi_pcihp_eject_slot(,slots = 0)
uinst32_t slot = ctz32(slots)
...
... = ~(1U << slot)
where 'slot' value is 32 in case 'slots' bitmap is empty.
'slots' is a bitmap and empty one shouldn't do anything
so return early doing nothing if resulted slot value is
not valid (i.e. not in 0-31 range)
