Fix FAST_ExtInfw_Restart API

[marchdf]

The C++ function declaration had an extra argument InflowType, that is not present in the Fortran function definition.

thanks for catching this! We'll get this into 4.1.0

Longer description from @marchdf:

Short story: on calling that restart function, we got invalid returns in the C++. num_blades would be ridiculous, the error code nonsensical (like ierr = 538976256)

We wrap OF function calls with a function that check the error id. It was returning a wild error ID and so we were aborting. But it didn't have a message attached (which it would if it error "properly"). So then I started printing the error code in the fortran code and in the c++ code and they didn't match. And then I noticed that we were somehow getting 19 blades returned in the c++ whereas the fortran was saying there were 3. So I thought it was some kind of memory corruption. I took another look at the function signature in the fortran and got really confused that amr-wind had the extra inflow argument in the amr-wind function call. I couldn't understand why we would have it if it wasn't in the function definition. So I removed it and then compilation broke. More confusion. And then I compared it to the c++ function declaration and noticed that the arguments didn't match in the declaration and definition. It was a process 🙃
