f2fs: fix start segno of large section
[ Upstream commit 8c409989678e92e4a737e7cd2bb04f3efb81071a ]
get_ckpt_valid_blocks() checks valid ckpt blocks in current section.
It counts all vblocks from the first to the last segment in the
large section. However, START_SEGNO() is used to get the first segno
in an SIT block. This patch fixes that to get the correct start segno.
