Fix T52439: Crash after adjusting lenght of hair particles. 

Regression from rBfed853ea78221, calling this inside thread worker was
not really good idea anyway, and we already have all the code we need in
pre-threading init function, was just disabled for vertex particles
before.

To be backported to 2.79.
