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.
