LU-1199 build: Remove duplicate LC_MODULE_LOADING

It appears that LC_MODULE_LOADING was accidentally declared twice
back-to-back in the same file.  This removes the first declaration
on the assumption that if my eye-balling of the code missed a
difference, the second one is the one we've been using anyway.
