job: Fix off-by-one assert checks for JobSTT and JobVerbTable

In the assert checking the array dereference of JobVerbTable[verb]
in job_apply_verb() the check of the index, verb, allows an overrun
because an index equal to the array size is permitted.

Similarly, in the assert check of JobSTT[s0][s1] with index s1
in job_state_transition(), an off-by-one overrun is not flagged
either.

This is not a run-time issue as there are no callers actually
passing in the max value.
