Summary
md/raid10: fix leak of 'r10bio->remaining' for recovery
Details

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

md/raid10: fix leak of 'r10bio->remaining' for recovery

raid10syncrequest() will add 'r10bio->remaining' for both rdev and replacement rdev. However, if the read io fails, recoveryrequestwrite() returns without issuing the write io, in this case, endsyncrequest() 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.
