arm64: vdso: Pass (void *) to virt_to_page() 

[ Upstream commit b0abde8062 ]

Like the other calls in this function virt_to_page() expects
a pointer, not an integer.

However since many architectures implement virt_to_pfn() as
a macro, this function becomes polymorphic and accepts both a
(unsigned long) and a (void *).

Fix this up with an explicit cast.
