Subject: raid10: increment write counter after bio is split

From: Tomasz Majchrzak <tomasz.majchrzak@intel.com>

commit 9b622e2bbcf049c82e2550d35fb54ac205965f50 upstream.

md pending write counter must be incremented after bio is split,
otherwise it gets decremented too many times in end bio callback and
becomes negative.
