scripts/kernel-doc: drop "_noprof" on function prototypes
Memory profiling introduces macros as hooks for function-level allocation profiling[1]. Memory allocation functions that are profiled are named like xyz_alloc() for API access to the function. xyz_alloc() then calls xyz_alloc_noprof() to do the allocation work. The kernel-doc comments for the memory allocation functions are introduced with the xyz_alloc() function names but the function implementations are the xyz_alloc_noprof() names. This causes kernel-doc warnings for mismatched documentation and function prototype names. By dropping the "_noprof" part of the function name, the kernel-doc function name matches the function prototype name, so the warnings are resolved.
