f2fs: allocate memory in batch in build_sit_info()
build_sit_info() allocate all bitmaps for each segment one by one, it's quite low efficiency, this pach changes to allocate large continuous memory at a time, and divide it and assign for each bitmaps of segment. For large size image, it can expect improving its mount speed.
