[PATCH v2] f2fs: fix to use correct segment type in f2fs_allocate_data_block()

[Chao Yu]

@type in f2fs_allocate_data_block() indicates log header's type, it
can be CURSEG_COLD_DATA_PINNED or CURSEG_ALL_DATA_ATGC, rather than
type of data/node, however IS_DATASEG()/IS_NODESEG() only accept later
one, fix it.

Fixes: 093749e296e2 ("f2fs: support age threshold based garbage collection")

v2:
- use curseg->seg_type instead of se->type due to se is valid only
in atgc allocation context.
