xen/acpi: off by one in read_acpi_id()
[ Upstream commit c37a3c94775855567b90f91775b9691e10bd2806 ]
If acpi_id is == nr_acpi_bits, then we access one element beyond the end
of the acpi_psd[] array or we set one bit beyond the end of the bit map
when we do __set_bit(acpi_id, acpi_id_present);
Fixes: 59a568029181 ("xen/acpi-processor: C and P-state driver that uploads said data to hypervisor.")
