Subject: [PATCH v3] f2fs: fix to parse temperature correctly in f2fs_get_segment_temp()
In __get_segment_type(), __get_segment_type_6() may return
CURSEG_COLD_DATA_PINNED or CURSEG_ALL_DATA_ATGC log type, but
following f2fs_get_segment_temp() can only handle persistent
log type, fix it.
Signed-off-by: Chao Yu <chao@...nel.org>

v3:
- initialize type variable in __get_segment_type()
