md/raid10: fix writes_pending and barrier reference leaks on discard failures

In the Linux kernel, the following vulnerability has been resolved:

md/raid10: fix writes_pending and barrier reference leaks on discard failures

raid10_make_request() acquires a writes_pending reference with
md_write_start() before calling raid10_handle_discard(). Several failure
paths in raid10_handle_discard() complete the bio and return without
releasing the corresponding reference, causing md_write_end() to be
skipped.

Call md_write_end() before returning from these failure paths to keep
writes_pending accounting balanced.

Additionally, discard split allocation failures can occur after
wait_barrier() succeeds. Those paths return without calling
allow_barrier(), leaking the associated barrier reference.

Release the barrier before returning from those paths.
