Make sure to define state_vector if not in land use mode

[glemieux]

Description:

This is a bug fix for #1221 which came in with the latest tag sci.1.77.0_api.36.0.0. The local variable state_vector is undefined in disturbance_rates if land use mode is off. To avoid indexing into an array of NaN we need to define values for state_vector. The fix proposed here is to set it by getting the current state vector, which is called at the top of the subroutine.

this makes sense to me, thanks @glemieux.
