drm/xe: Fix END redefinition

mips declares an END macro in its headers so it can't be used without
namespace in a driver like xe.

Instead of coming up with a longer name, just remove the macro and
replace its use with 0 since it's still clear what that means:
set_offsets() was already using that implicitly when checking the data
variable.
