[FAB-10407] Fix an errMsg in vscc (cc deploy/upgr.)

Currently, during a chaincode deploy or upgrade, when more
than the required number of entries present in the lscc write set,
vscc throws the following error
"LSCC can only issue a single putState upon deploy/upgrade"

This CR differentiate the error message (for deploy and
upgrade) by either specifying "deploy" or "upgrade" but not both
