platform/x86/intel/vsec: free ACPI discovery data on early errors

platform/x86/intel/vsec: free ACPI discovery data on early errors

intel_vsec_add_dev() may attach an ACPI discovery table copy to the
intel_vsec_device before passing ownership to intel_vsec_add_aux(). The
normal auxiliary-device release path frees that copy, but the earliest
intel_vsec_add_aux() failures free only the outer structure directly.

Route those direct frees through a common helper so acpi_disc is
released consistently on the parent, xarray, and ID allocation failure
paths.
