extable: Make init_kernel_text() global
Convert init_kernel_text() to a global function and use it in a few
places instead of manually comparing _sinittext and _einittext.
Note that kallsyms.h has a very similar function called
is_kernel_inittext(), but its end check is inclusive. I'm not sure
whether that's intentional behavior, so I didn't touch it.
