[PATCH 5/5] staging: comedi: tests: Correct unittest_fptr

[Ian Abbott <abbotti@xxxxxxxxx>]

The definition of the `unittest_fptr` function pointer type has the
wrong function return type `void *` instead of `void`.  The problem is
hidden by a bunch of unnecessary type-casts.  Fix the type definition
and remove the type-casts.
