slimbus: fix slim_tid_txn()

slimbus: fix slim_tid_txn()

fix below issue reported by coccicheck
./drivers/slimbus/slimbus.h:440:3-46: duplicated argument to && or ||

Looks like this was a typo, SLIM_MSG_MC_REQUEST_CHANGE_VALUE is command
which requires transaction ID, so fix it, this also fix the warning.
