drivers/c/pwmControlFan.c: Fix NULL pointer deref #147

The reason why most if not all of the bug reports complain about this segfaulting is because this app segfaults if there is no config file.

This unfortunately doesn't solve the root causes that most people encounter, but this should remove some noise in all the issues.

as a result of this PR, the relevant binaries need updating (also make a 64bit Makefile64 maybe)

That's a good idea!
