Asm routines that end up having size equal to zero are not really zero
sized, and as now we do kernel_maps__fixup_sym_end, at least for kernel
routines this gets fixed.
A similar fixup needs to be done for the userspace bits as well, but as
this fixup started only because in /proc/kallsyms we don't have the end
address nor the function size, it appeared here first.
