The ivrs_acpihid command-line parser appends entries to a fixed
four-element early_acpihid_map array. Unlike the sibling IOAPIC and HPET
parsers, it does not reject a fifth entry before incrementing the map size.
Check the capacity at the common found label before parsing the HID and
UID or writing the entry.
Fixes: ca3bf5d47c ("iommu/amd: Introduces ivrs_acpihid kernel parameter")
