xen/pvcalls-back: fix double frees with pvcalls_new_active_socket()
In the pvcalls_new_active_socket() function, most error paths call
pvcalls_back_release_active(fedata->dev, fedata, map) which calls
sock_release() on "sock". The bug is that the caller also frees sock.
Fix this by making every error path in pvcalls_new_active_socket()
release the sock, and don't free it in the caller.
