W3UNO2MD OMP bug fix

[ukmo-ccbunney]

Reference issue #169
Fixes bug where OMP directive fails to compile due to undefined QOLD variable if T2 switch is not enabled.

@aliabdolali I've included you as reviewer for this PR: this is a bugfix that would in my view not require a full regtest, only perhaps regtests that use the UNO and OMP switches. @ukmo-ccbunney for the record would you be able to run those tests and provide summary of results? Thanks!

@ukmo-ccbunney for the record would you be able to run those tests and provide summary of results?

@ajhenrique - Sure. As far as I can tell, it is just the mww3_test_05 and ww3_ts3 regtests that are affected.

Matrix comparison of relevant regtests with my previous regtest baseline run (commit fbebf9) shows all tests are identical.

Looks good! Thanks for adding the regtests outputs.
