cap_prctl: don't set error to 0 at 'no_change'

One-liner: capsh --print is broken without this patch.

In certain cases, cap_prctl returns error > 0 for success.  However,
the 'no_change' label was always setting error to 0.  As a result,
for example, 'prctl(CAP_BSET_READ, N)' would always return 0.
It should return 1 if a process has N in its bounding set (as
by default it does).

I'm keeping the no_change label even though it's now functionally
the same as 'error'.
