module: don't modify argument of module_kallsyms_lookup_name()
If we pass a pointer to a const string in the form "module:symbol" module_kallsyms_lookup_name() will try to split the string at the colon, i.e., will try to modify r/o data. That will, in fact, fail on a kernel with enabled CONFIG_DEBUG_RODATA. Avoid modifying the passed string in module_kallsyms_lookup_name(), modify find_module_all() instead to pass it the module name length.
