New NEON initial conditions needed

### Brief summary of bug

run_neon cases fail out of the box because restart files don't have excess ice information, which is on by default for CTSM5.3.

### General bug information

**CTSM version you are using:** [output of `git describe`]
Reported by @ advyth the case directory is here /glade/derecho/scratch/advyth/NEON_cases/SJER.transient. The lnd.log aborts with this error.
```
This input initial conditions file does NOT include excess ice fields, and use_
excess_ice_streams is off, one or the other needs to be changed ERROR in Water
StateType.F90 at line 757
```

In the short term, a simple fix could be to add the following to user_nl_clm `use_excess_ice = .false.`

Long term, hopefully this can be addressed after we bring in #2406, and maybe in conjunction with #2739.
