x86/vmware: Correct macro names
VCPU_RESERVED and LEGACY_X2APIC are not VMware hypercall commands. These are
bits in the return value of the VMWARE_CMD_GETVCPU_INFO command. Change
VMWARE_CMD_ prefix to GETVCPU_INFO_ one. And move the bit-shift
operation into the macro body.
Fixes: 4cca6ea04d31c ("x86/apic: Allow x2apic without IR on VMware platform")
