Subject: - If swap metadata does not fit into the KVM, reduce the number of
 struct swblock entries by dividing the number of the entries by 2 until the
 swap metadata fits.

- Reject swapon(2) upon failure of swap_zone allocation.

This is just a temporary fix. Better solutions include:
(suggested by:	dillon)

o reserving swap in SWAP_META_PAGES chunks, and
o swapping the swblock structures themselves.
