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.
