module: Remove the unused function within

The function within is defined in the main.c file, but not called
elsewhere, so remove this unused function.

This routine became no longer used after commit ("module: replace
module_layout with module_memory").

kernel/module/main.c:3007:19: warning: unused function 'within'.
