md/raid10: use correct limit variable

commit 91502f099dfc5a1e8812898e26ee280713e1d002 upstream.

Clang complains that we are assigning a variable to itself.  This should
be using bad_sectors like the similar earlier check does.

Bug has been present since 3.1-rc1.  It is minor but could
conceivably cause corruption or other bad behaviour.
