update for getting the glc present flag set correctly with nag compiler

### Description of changes
update for getting the glc present flag set correctly with nag compiler

### Specific notes
The following ctsm test - SMS_D_Ld5_Vnuopc.f10_f10_mg37.I2000Clm50BgcCrop.izumi_nag.clm-irrig_alternate passed on cheyenne with intel but failed on izumi with nag. This bugfix corrects the if-present logic for GLC and permits the test to successfully pass now on izumi.

Contributors other than yourself, if any:

CMEPS Issues Fixed: None 

Are changes expected to change answers?
 - [x] bit for bit
 - [ ] different at roundoff level
 - [ ] more substantial 

Any User Interface Changes (namelist or namelist defaults changes)?
 - [ ] Yes
 - [x] No

Testing performed if application target is CESM:(either UFS-S2S or CESM testing is required):
ran SMS_D_Ld5_Vnuopc.f10_f10_mg37.I2000Clm50BgcCrop.izumi_nag.clm-irrig_alternate successfully on izumi.
