In cost-benefit GC algorithm, mtime will affect
the selection of victim segment.For a large section,
mtime should be the mean value of valid segments,
in order to select correct victim segment,
it needs to modify the calculation method of mtime.

v2:
- modify new API:get_section_mtime

liuderong (2):
  f2fs: remove unused parameters
  f2fs: introduce get_section_mtime
