Dan Carpenter c60f38c9bd xen/pvcalls-back: fix double frees with pvcalls_new_active_socket()
commit 8fafac202d18230bb9926bda48e563fd2cce2a4f upstream.

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.

Fixes: 5db4d286a8 ("xen/pvcalls: implement connect command")
