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.
