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).
Fixes: commit b288cd960072 ("x86: acpi: Generate SPCR table")
