f2fs: avoid redundant call to has_not_enough_free_secs in f2fs_gc
After doing a write_checkpoint from garbage collection path if there is still need to do more garbage collection, gc_more label is used to jump and start the process again. And in that process, first step before getting victim is to check if there are not enough free sections, which is already done before doing a jump to gc_more. We can avoid the redundant call to check free sections, by checking the gc_type flag which will remain FG_GC(value 1) under this condition.
