r222015 introduced a new assertion that the size of a fixed-length sbuf
buffer is greater than 1.  This triggered panics in at least one spot in
the kernel (the MAC Framework) which passes non-negative, rather than >1
buffer sizes based on the size of a user buffer passed into a system
call.  While 0-size buffers aren't particularly useful, they also aren't
strictly incorrect, so loosen the assertion.
