Andrey Konovalov 8f6a7f96dc vhost, kcov: collect coverage from vhost_worker
Add kcov_remote_start()/kcov_remote_stop() annotations to the
vhost_worker() function, which is responsible for processing vhost
works.

Since vhost_worker() threads are spawned per vhost device instance the
common kcov handle is used for kcov_remote_start()/stop() annotations
(see Documentation/dev-tools/kcov.rst for details).  As the result kcov
can now be used to collect coverage from vhost worker threads.
