bcachefs: Fix allocate -> self healing path
When we go to allocate and find taht a bucket in the freespace btree is
actually allocated, we're supposed to return nonzero to tell the
allocator to skip it.
This fixes an emergency read only due to a bucket/ptr gen mismatch - we
also don't return the correct bucket gen when this happens.
