ash: jobs: Don't attempt to access job table for job %0
Upstream commit: jobs: Don't attempt to access job table for job %0 If job %0 is (mistakenly) specified, an out-of-bounds access to the jobtab occurs in function getjob() if num = 0: jp = jobtab + 0 - 1 Fix this by checking that the job number is larger than 0 before accessing the jobtab.
