md/raid5: don't test ->writes_pending in raid5_remove_disk
This test on ->writes_pending cannot be safe as the counter
can be incremented at any moment and cannot be locked against.
Change it to test conf->active_stripes, which at least
can be locked against. More changes are still needed.
A future patch will change ->writes_pending, and testing it here will
be very inconvenient.
