[PATCH v2] examples/vhost: fix the wrong initialization of lcore_ids

[Yong Wang]

when "TAILQ_INIT()" was added to the loop of "for (lcore_id = 0; ...)"
statement, the assignment to "lcore_ids" was removed out of the loop.
It changed the original initialization of "lcore_ids".

Fix it by introducing two braces.

Fixes: 45657a5c6861 ("examples/vhost: use tailq to link vhost devices")

v2:
* fix the coding style error of '++'.
