x86/mm: Use the correct function type for native_set_fixmap()
[ Upstream commit f53e2cd0b8ab7d9e390414470bdbd830f660133f ]
We call native_set_fixmap indirectly through the function pointer
struct pv_mmu_ops::set_fixmap, which expects the first parameter to be
'unsigned' instead of 'enum fixed_addresses'. This patch changes the
function type for native_set_fixmap to match the pointer, which fixes
indirect call mismatches with Control-Flow Integrity (CFI) checking.
