When the function blist_fill() was added to the kernel in r107913, the swap
pager used a different scheme for striping the allocation of swap space
across multiple devices.  And, although blist_fill() was intended to support
fill operations with large counts, the old striping scheme never performed a
fill larger than the stripe size.  Consequently, the misplacement of a
sanity check in blst_meta_fill() went undetected.  Now, moving forward in
time to r118390, a new scheme for striping was introduced that maintained a
blist allocator per device, but as noted in r318995, swapoff_one() was not
fully and correctly converted to the new scheme.  This change completes what
was started in r318995 by fixing the underlying bug in blst_meta_fill() that
stops swapoff_one() from simply performing a single blist_fill() operation.
