module: Use RCU in find_kallsyms_symbol().
The modules list and module::kallsyms can be accessed under RCU
assumption.
Use rcu_dereference() to reference the kallsyms pointer in
find_kallsyms_symbol(). Use a RCU section instead of preempt_disable in
callers of find_kallsyms_symbol(). Keep the preempt-disable in
module_address_lookup() due to __module_address().
