msm: vidc: use %pK instead of %p which respects kptr_restrict sysctl

Hide kernel pointers from unprivileged ussers by using %pK format-
specifier instead of %p. This respects the kptr_restrict sysctl
setting which is by default on. So by default %pK will print zeroes
as address. echo 1 to kptr_restrict to print proper kernel addresses.
