New NEON initial conditions needed

[wwieder]

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.
