Bluetooth: Replace %p with %pK
The %pK restrictions are used to eliminate exposing kernel addresses.
When kptr_restrict is set to "0" there are no restrictions. When
kptr_restrict is set to "1", kernel pointers printed using the %pK
format specifier will be replaced with 0's unless the user has
CAP_SYSLOG. When kptr_restrict is set to "2", kernel pointers printed
using %pK will be replaced with 0's regardless of privileges.
