bug#30253: Fix for bug 21062 coreutils-8.24 - cp(1) check failures on tmpfs filesystem (Solaris 10 / Solaris 11)

[Alexander Pyhalov]

Hello.

I have a fix for 'bug 21062 coreutils-8.24 - cp(1) check failures on 
tmpfs filesystem (Solaris 10 / Solaris 11)'.

The issue is that when on tmpfs we use acl(), trying to set ACL, it sets 
errno to ENOSYS (ACLs not supported).
set_acls still returns 0, but it spoils errno. When we do "cp -a", later 
this ENOSYS appears in set_acls() results.
(I still don't quite understand, why return code is not 0).
The easiest fix here is to resetting errno to 0 when we are not going to 
return non-zero result immediately
