Thomas Gleixner 781c64bfcb x86/fpu/xstate: Handle supervisor states in XSTATE permissions 
The size calculation in __xstate_request_perm() fails to take supervisor
states into account because the permission bitmap is only relevant for user
states.

Up to 5.17 this does not matter because there are no supervisor states
supported, but the (re-)enabling of ENQCMD makes them available.

Fixes: 7c1ef59145 ("x86/cpufeatures: Re-enable ENQCMD")
