mm/kmemleak: use %pK to display kernel pointers in backtrace
Currently, %p is used to display kernel pointers in backtrace which result in a hashed value that is not usable to correlate the address for debug. Use %pK which will respect the kptr_restrict configuration value and thus allow to extract meaningful information from the backtrace.
