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_*). Tx path is already merged to net, so it
was excluded from patchset in v4. 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.

Changelog:
v1 -> v2:
- Add patch for VMCI as Vishnu Dasa suggested.
v2 -> v3:
- Change type of 'err' var in VMCI patches from 'int' to 'ssize_t'.
- Split VMCI patch to two patches: for send and for receive cases.
- Reorder patches: move VMCI before af_vsock.c.
v3 -> v4:
- Exclude VMCI patch for send from patchset (merged to 'net').
- Update commit message of VMCI patch for receive.
