acpi_spmc: fix revision check reading name as integerHEADmain

In acpi_spmc_get_constraints_spec(), the revision of the device
constraint detail package was mistakenly read from
constraint_obj->Package.Elements[0], which is the device name
(a string), instead of from the detail sub-package's first element.

Move the initialisation of 'detail' before the revision check and
read the revision from detail->Package.Elements[0] as the comment
already states
