Xi Ruoyao 8031772e5a x86/mm: Don't disable PCID when INVLPG has been fixed by microcode 
commit f24f669d03 upstream.

Per the "Processor Specification Update" documentations referred by
the intel-microcode-20240312 release note, this microcode release has
fixed the issue for all affected models.

So don't disable PCID if the microcode is new enough.  The precise
minimum microcode revision fixing the issue was provided by Pawan
Intel.
