f2fs: fix wrong total_sections check and fsmeta check

Browse Source 
Meta area is not included in section_count computation.
So the minimum number of total_sections is 1 meanwhile it cannot be
greater than segment_count_main.

The minimum number of meta segments is 8 (SB + 2 (CP + SIT + NAT) + SSA).
