Subject[patch 10/26] Fix error returns in sys_socketpair()
2.6.22-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: David Miller <davem@davemloft.net>

patch bf3c23d171e35e6e168074a1514b0acd59cfd81a in mainline.

[NET]: Fix error reporting in sys_socketpair().

If either of the two sock_alloc_fd() calls fail, we
forget to update 'err' and thus we'll erroneously
return zero in these cases.

Based upon a report and patch from Rich Paul, and
commentary from Chuck Ebbert.
