mm/kmemleak: use %pK to display kernel pointers in backtrace

Browse source 
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.
