lib/lzmadecode.c: : Avoid static analysis error for unused value
Within procedure LzmaDecode(), the variable len can be assigned a value
that is never read after, thus causing a static analysis error. Tell the
coreboot scan-build static analysis we know it can happen.
BUG=b:112253891
TEST=Build and boot grunt.
