Subject: [PATCH v11 6/8] x86/vmware: Correct macro names

VCPU_RESERVED and LEGACY_X2APIC are not VMware hypercall commands.
These are bits in return value of VMWARE_CMD_GETVCPU_INFO command.
Change VMWARE_CMD_ prefix to GETVCPU_INFO_ one. And move bit-shift
operation to the macro body.

Fixes: 4cca6ea04d31c ("x86/apic: Allow x2apic without IR on VMware platform")
