Subject: [PATCH] vhost: fix error code check when creating thread

[ upstream commit da51d2f6b8b652da8eb9d4b50df4f3f5a24b656f ]

On error, pthread_create() returns a positive number (errno).
Fix the test on the return value.

Fixes: af1475918124 ("vhost: introduce API to start a specific driver")
Fixes: e623e0c6d8a5 ("vhost: add reconnect ability")
