LCLS: explicitly check for *CX adjustment

Previously the expectations for number of CRCX and MDCX messages from
MGW was adjusted unconditionally for LCLS tests. However this is only
necessary for MGW-loop type of LCLS. Use explicit variable (with default
value preserving current behavior) to decide whether to apply this
adjustment or not. This simplifies support for other kinds of LCLS
loops.
