KVM: VMX: Combine "check" and "get" APIs for passthrough MSR lookups
Combine possible_passthrough_msr_slot() and is_valid_passthrough_msr()
into a single function, vmx_get_passthrough_msr_slot(), and have the
combined helper return the slot on success, using a negative value to
indicate "failure".
Combining the operations avoids iterating over the array of passthrough
MSRs twice for relevant MSRs.
