arm64/vdso: don't leak kernel addresses
Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"),
two obfuscated kernel pointer are printed at every boot:
vdso: 2 pages (1 code @ (____ptrval____), 1 data @ (____ptrval____))
Remove the the print completely, as it's useless without the addresses.
Fixes: ad67b74d2469d9b8 ("printk: hash addresses printed with %p")
