mm/mglru: drop unused parameter

Patch series "mm/mglru: code cleanup and refactoring"

This provides MGLRU code cleanup and refactoring for better readability.

This patch (of 5):

struct scan_control *sc is currently passed into try_to_inc_max_seq() and
run_aging().  This parameter is not used.

Drop the unused parameter struct scan_control *sc. No functional change.
