[PATCH 2/2] x86: acpi: Add memset to initialize SPCR table

[Wolfgang Wallner]

Add a missing memset to acpi_create_spcr().

The other acpi_create_xxxx() functions perform a memset on their
structures, acpi_create_spcr() does not and as a result the contents of
this table are partly uninitialized (and thus random after every reset).
