ACPI: processor: fix acpi_object initialization

Initialization of the local acpi_object in acpi_processor_get_info()
only sets the first 4 bytes to zero and is thus incomplete. This is
indicated by messages like:
	acpi ACPI0007:be: Invalid PBLK length [166288104]

Fix this by initializing all 16 bytes of the processor member of that
union.
