Fixes gcc '-Wunused-but-set-variable' warning:
mm/madvise.c: In function 'madvise_inject_error': mm/madvise.c:882:15: warning: unused variable 'zone' [-Wunused-variable]
After 4b63fdbe2b25 ("mm: remove the now-unnecessary mmget_still_valid() hack"), variable 'zone' is never used. Remove it to avoid build warning.
