asm-generic: Refactor dereference_[kernel]_function_descriptor()
dereference_function_descriptor() and
dereference_kernel_function_descriptor() are identical on the
three architectures implementing them.
Make them common and put them out-of-line in kernel/extable.c
which is one of the users and has similar type of functions.
