Roland McGrath 14dd0b8141 do_wait: return security_task_wait() error code in place of -ECHILD ...

This reverts the effect of commit f2cc3eb133
"do_wait: fix security checks".  That change reverted the effect of commit
7324328446.  The rationale for the original
commit still stands.  The inconsistent treatment of children hidden by
ptrace was an unintended omission in the original change and in no way
invalidates its purpose.

This makes do_wait return the error returned by security_task_wait()
(usually -EACCES) in place of -ECHILD when there are some children the
caller would be able to wait for if not for the permission failure.  A
permission error will give the user a clue to look for security policy
problems, rather than for mysterious wait bugs.
