Update GFL to its latest with bug fixes

[weiwangncar]

TYPE: bug fix

KEYWORDS: GFL, seg fault

SOURCE: Haiqin Li and internal

DESCRIPTION OF CHANGES:
Three dimensional Qc and Qi were not passed to the GFL scheme where they are used to compute cloud fraction by the CPS. This PR points to an updated GFL where cloud fraction as well as reflectivity due to the CPS are disabled for now in WRF.

LIST OF MODIFIED FILES:
Only update the pointer to the GFL repository

TESTS CONDUCTED:

1. Tests are run on NOAA HPC and Derecho and seg fault problem is resolved.
2. The Jenkins tests all passing.

RELEASE NOTE:

[dudhia]

It comments out a cloud frcation calculation?

[weiwangncar]

@dudhia Yes. Because it requires 3D Qc and Qi which Haiqin didn't pass in to the scheme. He could choose to add those arrays, but it will also mean it needs to make sure the radiation will take it. I guess he just chose not to do it.

[dudhia]

So that cloud fraction is disabled?

[weiwangncar]

@dudhia I'm not sure how they do it now. @haiqinli ?

So that cloud fraction is disabled?

Yes, we don't have convective clouds & radiation coupling in WRF. We can do it later with some tunings.
