Subject: [PATCH 20/45] Only print debug message when failed to serach for
 kernel symbol from /proc/kallsyms

Kernel symbol page_offset_base could be unavailable when mm KASLR code is
not compiled in kernel. It's inappropriate to print out error message
when failed to search for page_offset_base from /proc/kallsyms. Seems now
there is not a way to find out if mm KASLR is compiled in or not. An
alternative approach is only printing out debug message in get_kernel_sym
if failed to search a expected kernel symbol.

Do it in this patch, a simple fix.
