CVE: NA

Intel-SIG: commit 02b93c0b x86/fpu: Get rid of using_compacted_format().

--------------------------------

This function is pointlessly global and a complete misnomer because it's
usage is related to both supervisor state checks and compacted format
checks. Remove it and just make the conditions check the XSAVES feature.
