md/raid1 - don't assume newly allocated bvecs are initialised.

Since commit d3f761104b097738932afcc310fbbbbfb007ef92
newly allocated bvecs aren't initialised to NULL, so we have
to be more careful about freeing a bio which only managed
to get a few pages allocated to it.  Otherwise the resync
process crashes.

This patch is appropriate for 2.6.29-stable.
