f2fs: fix to not account invalid blocks in get_left_section_blocks()

Browse source

commit 37345eae9d upstream.

w/ LFS mode, in get_left_section_blocks(), we should not account the
blocks which were used before and now are invalided, otherwise those
blocks will be counted as freed one in has_curseg_enough_space(), result
in missing to trigger GC in time.

Fixes: 249ad438e1 ("f2fs: add a method for calculating the remaining blocks in the current segment in LFS mode.")
Fixes: bf34c93d26 ("f2fs: check curseg space before foreground GC")
