Doug Moore 77555b849d Change the check for 'size' wrapping around to zero in kern_mmap to account
for both the lower and upper bound modifications. Change the error returned
to ENOMEM. Rename the parameter size to len and make size a local variable
that stores the value of len after it has been modified.

This addresses concerns expressed by Bruce Evans after r348843.
