Remove compiler warnings

[JessicaMeixner-NOAA]

Describe the bug
For a few regression tests, depending on the switch we have a compiler warning:

ww3_tp1.8/work_BJ_PR3_UQ/build.log:215:/scratch1/NCEPDEV/climate/Jessica.Meixner/PR_WW3/pr1201/model/src/w3wavemd.F90(1589): warning #6371: A jump into a block from outside the block may have occurred.   [370]

These all appear to be related and with a particular GO TO statement in the code.

The tp2.19 switch file is:
PDLIB METIS NOGRB DIST MPI PR3 UQ FLX0 LN0 ST0 NL0 BT0 DB1 TR1 BS0 IC0 IS0 REF0 WNT1 WNX1 CRT1 CRX1 SEC1 O0 O1 O2 O3 O4 O5 O6 O7

And the tp1.8 switch file is:
NOGRB SHRD PR3 UQ FLX0 LN1 ST4 NL0 BT1 DB0 MLIM TR0 BS0 IC0 IS0 REF0 WNT1 WNX1 CRT1 CRX1 SEC1 O0 O1 O2 O3 O4 O5 O6 O7 O10 O11

To Reproduce
Run all the regression tests, and then grep the build.log files for warning.

Expected behavior
Ideally, we should have no compiler warnings when building.

Screenshots
n/a

Additional context
I believe the SEC1 is the unique item here from other regression tests.
