vsock: return errors other than -ENOMEM to socket

[Arseniy Krasnov]

Hello,

this patchset removes behaviour, where error code returned from any
transport was always switched to ENOMEM. This works in the same way as
patch from Bobby Eshleman:
commit c43170b7e157 ("vsock: return errors other than -ENOMEM to socket"),
but for receive calls. VMCI transport is also updated (both tx and rx
SOCK_STREAM callbacks), because it returns VMCI specific error code to
af_vsock.c (like VMCI_ERROR_*). At the same time, virtio and Hyper-V
transports are using general error codes, so there is no need to update
them.

vsock_test suite is also updated.

Link to v1:

Changelog:

v1 -> v2:
 - Add patch for VMCI as Vishnu Dasa suggested.
