[PATCH 7/9] x86/hvm: address violations of MISRA C:2012 Rule 11.8

[Simone Ballarin <simone.ballarin@xxxxxxxxxxx>]

From: Maria Celeste Cesario <maria.celeste.cesario@xxxxxxxxxxx>

The xen sources contain violations of MISRA C:2012 Rule 11.8 whose
headline states:
"A conversion shall not remove any const, volatile or _Atomic qualification
from the type pointed to by a pointer".

Remove unnecessary cast.
from is a const-qualified pointer to void and the function 
hvm_copy_to_guest_linear
requires a const void* type argument, therefore the cast to void* is not 
necessary.

No functional change.
