Test 071 was failing in weird ways, partly because it was trying
to pass in offsets larger than strtoll() could accept, which then
silently returned LLONG_MAX instead. For DIO tests, this was
unaligned, so we got unexpected (to me, anyay) alignment errors.
At least printing out the perror() makes this more obvious,
but unfortunately we then get the somewhat odd output:
# xfs_io -f -d -c "pwrite 9223373136366403584 4096" /mnt/test/grrr
cvtnum: Numerical result out of range
non-numeric offset argument -- 9223373136366403584
Test 071 still fails, but at least it's a bit more obvious as to why.

Note:
... should I change all callsites from "non-numeric" to "invalid" perhaps?
