json_pointer.c: Move idx_val declaration to top of function

Browse Source 
This helps compiling with MS compiler, error seems to be
due to defining a variable within the body of the function
its allowed in c99 but not in c89. This should fix build with
MSVC 16.0.40219.1 compiler from Visual Studio 14 2015
