Corinna Vinschen 2bbe8697d8 Cygwin: fix memory corruption/SEGV if certain socket functions fail
Regression introduced with 2.11.0:

The failure paths in socket, socketpair and accept4 functions and
methods accidentally release *unused* cygheap_fdmanip objects.  The
subsequently called dtable::release method was designed to be called for
*used* cygheap_fdmanip objects only.  Using them on unused objects leads
to NULL pointer member dereferencing.

Worse, the inet/local accept4 methods only release the cygheap_fdmanip
object but neglect to delete the just created fhandler_socket_* object.

Fix this by removing the erroneous release calls in the aforementioned
failure paths and delete the fhandler_socket_* object in accept4 instead.
