md/raid10: fix leak of 'r10bio->remaining' for recovery
[ Upstream commit 26208a7cffd0c7cbf14237ccd20c7270b3ffeb7e ]
raid10_sync_request() will add 'r10bio->remaining' for both rdev and
replacement rdev. However, if the read io fails, recovery_request_write()
returns without issuing the write io, in this case, end_sync_request()
is only called once and 'remaining' is leaked, cause an io hang.
Fix the problem by decreasing 'remaining' according to if 'bio' and
'repl_bio' is valid.
Fixes: 24afd80d99f8 ("md/raid10: handle recovery of replacement devices.")
