ARM: 8896/1: VDSO: Don't leak kernel addresses
Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with
%p"), an obfuscated kernel pointer is printed at every boot if
debugging is enabled:
vdso: 1 text pages at base (____ptrval____)
Remove the print completely, as it's useless without the address.
Based on commit 0f1bf7e39822476b ("arm64/vdso: don't leak kernel
addresses").
Fixes: ad67b74d2469d9b8 ("printk: hash addresses printed with %p")
