[PATCH] mei: vsc: Fix wrong invocation of ACPI SID method

[Hans de Goede]

When using an initializer for a union only one of the union members
must be initialized. The initializer for the acpi_object union variable
passed as argument to the SID ACPI method was initializing both
the type and the integer members of the union.

Unfortunately rather then complaining about this gcc simply ignores
the first initializer and only used the second integer.value = 1
initializer. Leaving type set to 0 which leads to the argument being
skipped by acpi acpi_ns_evaluate() resulting in:

ACPI Warning: \_SB.PC00.SPI1.SPFD.CVFD.SID: Insufficient arguments -
Caller passed 0, method requires 1 (20240322/nsarguments-232)

Fix this by initializing only the integer struct part of the union
and initializing both members of the integer struct.

Even though this is a one-liner, figuring out what was actually going
wrong here took quite a while.
