md/raid10: fix memory leak when reshaping a RAID10.
commit ce0b0a46955d1bb389684a2605dbcaa990ba0154 upstream. raid10 reshape clears unwanted bits from a bio->bi_flags using a method which, while clumsy, worked until 3.10 when BIO_OWNS_VEC was added. Since then it clears that bit but shouldn't. This results in a memory leak. So change to used the approved method of clearing unwanted bits. As this causes a memory leak which can consume all of memory the fix is suitable for -stable.
