usb: host: replace %p with %pK
Format specifier %p can leak kernel addresses while not valuing the
kptr_restrict system settings. When kptr_restrict is set to (1), kernel
pointers printed using the %pK format specifier will be replaced with 0's.
Debugging Note : &pK prints only Zeros as address. If you need actual
address information, write zero to kptr_restrict.
echo 0 > /proc/sys/kernel/kptr_restrict
