[PATCH 1/1] vhost_task: Fix vhost_task_create return value

[Mike Christie <michael.christie@oracle.com>]

vhost_task_create is supposed to return the vhost_task or NULL on
failure. This fixes it to return the correct value when the allocation
of the struct fails.

Fixes: 77feab3c4156 ("vhost_task: Allow vhost layer to use copy_process") # mainline only
