[PATCH] scripts/sorttable: guard long_size under MCOUNT_SORT_ENABLED

[Dakkshesh <beakthoven@gmail.com>]

clang's -Wunused-but-set-global (a sub-warning of
-Wunused-but-set-variable, enabled via -Wall), points out an
unused static global variable in scripts/sorttable.c:

scripts/sorttable.c:452:12: error: variable 'long_size' set but not
  used [-Werror,-Wunused-but-set-variable]

long_size is only read inside MCOUNT_SORT_ENABLED blocks. In upstream,
it is implicitly resolved by commit b055f4c431e3 ("sorttable: Move ELF
parsing into scripts/elf-parse.[ch]") which refactors the file entirely.
