nfit_test: improve structure offset handling
In nfit_test0_setup() and nfit_test1_setup() we keep an 'offset' value which we use to calculate where in our 'nfit_buf' we will place our next structure. The handling of 'offset' and the calculation of the placement of the next structure is a bit inconsistent, though. We don't update 'offset' after we insert each structure, sometimes causing us to update it for multiple structures' sizes at once. When calculating the position of the next structure we aren't always able to just use 'offset', but sometimes have to add in other structure sizes as well. Fix this by updating 'offset' after each structure insertion in a consistent way, allowing us to always calculate the position of the next structure to be inserted by just using 'nfit_buf + offset'.
