net/rds: Pass a pointer to virt_to_page()
Functions that work on a pointer to virtual memory such as
virt_to_pfn() and users of that function such as
virt_to_page() are supposed to pass a pointer to virtual
memory, ideally a (void *) or other pointer. However since
many architectures implement virt_to_pfn() as a macro,
this function becomes polymorphic and accepts both a
(unsigned long) and a (void *).
If we instead implement a proper virt_to_pfn(void *addr)
function the following happens (occurred on arch/arm):
net/rds/message.c:357:56: warning: passing argument 1
of 'virt_to_pfn' makes pointer from integer without a
cast [-Wint-conversion]
Fix this with an explicit cast.
