v11: Fix for lnfm.data symlink

[mathomp4]

@sshakoor1 found a bug in linkbcs where if CatchCN was on a symlink was incorrect:

> lt /discover/nobackup/projects/gmao/bcs_shared/fvInput/ExtData/esm/tiles/v11/CF0024x6C_DE1440xPE0720/lnfm_clim_24x144.data
"/discover/nobackup/projects/gmao/bcs_shared/fvInput/ExtData/esm/tiles/v11/CF0024x6C_DE1440xPE0720/lnfm_clim_24x144.data": No such file or directory (os error 2)

the line was missing the land/:

> lt /discover/nobackup/projects/gmao/bcs_shared/fvInput/ExtData/esm/tiles/v11/land/CF0024x6C_DE1440xPE0720/lnfm_clim_24x144.data

This fixes that path.

Not sure when this was missed, but the fix looks correct. Also not sure if this file is even used in CatchCN simulations. That'd require some digging, which isn't worth the effort. Perhaps @biljanaorescanin knows off the top of her head. I also don't know if anyone actually uses CatchCN with the GCM (as opposed to offline with GEOSldas) at this time.

In any case, best to merge the fix, it can't hurt.

@gmao-rreichle - lnfm (lightning frequency) is used with CatchCN.

I think the files specific to CatchCN from BCs are:
CLM_NDep_SoilAlb_T2m
CLM_veg_typs_fracs
lnfm.dat

• Maybe some scaling as well...depending how you setup run.

Not sure when this got broken... But tnx for fix @mathomp4 !
