f2fs: fix use-after-free of dicard command entry
As Dan Carpenter reported:
The patch 20ee4382322c: "f2fs: issue small discard by LBA order" from
Jul 8, 2018, leads to the following Smatch warning:
fs/f2fs/segment.c:1277 __issue_discard_cmd_orderly()
warn: 'dc' was already freed.
See also:
fs/f2fs/segment.c:2550 __issue_discard_cmd_range() warn: 'dc' was already freed.
In order to fix this issue, let's get error from __submit_discard_cmd(),
and release current discard command after we referenced next one.
