[PATCH] acpi: method: _CST test checks for wrong number of package elements

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

After running this through some of the various tables in my collection
I discovered that the _CST test checks for the number of elements
incorrectly.  This fixes an off-by-one error.
