This a limit of ncview, which is using the values of lat,lon from the 2d file. 
The CLM is land model, so works ONLY on land points, i.e. the ocean points are 
missing from its output (and input). The lat,lon variables in the file have 
missing points and cannot be used for geolocation.

You can use nevertheless xlat,xlon from a model output file to geolocate the data:

ncks -v xlat,xlon file_SRF.YYYYYMMDDHH.nc coord.nc
ncks -A coord.nc file.clm.h0.YYYYMM_2d.nc
ncatted -a coordinates,regcm_mask,c,c,'xlat xlon' file.clm.h0.YYYYMM_2d.nc

Note that being all variables defined just on land, the only variable for which 
you may be able to actually see in ncview the coastline is the regcm_mask...
