[PATCH for-5.0? 2/3] scripts/kernel-doc: Add missing close-paren in c:function directives

[Peter Maydell]

When kernel-doc generates a 'c:function' directive for a function
one of whose arguments is a function pointer, it fails to print
the close-paren after the argument list of the function pointer
argument, for instance:
  .. c:function:: void memory_region_init_resizeable_ram (MemoryRegion * mr, 
struct Object * owner, const char * name, uint64_t size, uint64_t max_size, 
void (*resized) (const char*, uint64_t length, void *host, Error ** errp)

which should have a ')' after the 'void *host' which is the
last argument to 'resized'.

Older versions of Sphinx don't try to parse the argumnet
to c:function, but Sphinx 3.0 does do this and will complain:

  
/home/petmay01/linaro/qemu-from-laptop/qemu/docs/../include/exec/memory.h:834: 
WARNING: Error in declarator or parameters
  Invalid C declaration: Expecting "," or ")" in parameters, got "EOF". [error 
at 208]
    void memory_region_init_resizeable_ram (MemoryRegion * mr, struct Object * 
owner, const char * name, uint64_t size, uint64_t max_size, void (*resized) 
(const char*, uint64_t length, void *host, Error ** errp)
    
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------^

Add the missing close-paren.
