Igor Mammedov a3ec4bb7e5 acpi: pcihp: fix left shift undefined behavior in acpi_pcihp_eject_slot()
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)
