Fixed a bug in CLM related to NaNs when using PGI on Titan.

A B1850C5L45BGC and ICLM45BGC case ran successfully after this fix on Titan,
when compiled with PGI. This commit resolves #165.

I realized that I made fews mistakes in this PR and PR #174:

• I created a branch from head rather than HASH that introduced the bug, and
• The name of the branch doesn't follow the naming convention.

For both PRs, the starting HASH should have been b7663ce. How do I fix both PRs?

[bishtgautam]

I was able to fix both the issues by the following commands

# 1) Rebase the branch from the correct starting hash
> git checkout bishtgautam/lnd/intel-14x-bugfix
# Determine the parent hash
> git log --pretty="%h %p" -n 1
830d81d cab58cf
# Change the parent of '830d81d' to be 'b7663ce' instead of 'cab58cf' 
> git rebase --onto b7663ce cab58cf
# Push the change in the remote
> git push origin bishtgautam/lnd/intel-14x-bugfix -f

# 2) Rename branch
> git branch -m bishtgautam/lnd/intel-14x-bugfix bishtgautam/lnd/bug-fix-intel-14x
> git push origin :bishtgautam/lnd/intel-14x-bugfix
> git push origin bishtgautam/lnd/bug-fix-intel-14x

Since the branches were deleted, the existing PRs were automatically deleted. I have created two new PRs.
