ACPI: processor: fix acpi_object initialization
[ Upstream commit 13edf7539211d8f7d0068ce3ed143005f1da3547 ]
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.
