f2fs: do not set free of current section 



For the case when sbi->segs_per_sec > 1, take section:segment = 5 for
example, if segment 1 is just used and allocate new segment 2, and the
blocks of segment 1 is invalidated, at this time, the previous code will
use __set_test_and_free to free the free_secmap and free_sections++,
this is not correct since it is still a current section, so fix it.
