swiotlb: use the right nslabs-derived sizes in swiotlb_init_late

nslabs can shrink when allocations or the remap don't succeed, so make
sure to use it for all sizing.  For that remove the bytes value that
can get stale and replace it with local calculations and a boolean to
indicate if the originally requested size could not be allocated.
