mvsas: don't allow negative timeouts
There is a static checker warning here because "val" is controlled by
the user and we have a upper bound on it but allow negative numbers.
"val" appears to be a timeout in usec so this bug probably means we
have a longer timeout than we should. Let's fix this by changing "val"
to unsigned.
