i965: Extend the negative 32-bit deltas to 64-bits

Gen8+ use 48-bit address relocations so need to extend the sign
to 64-bit return value. Without it we have higher bits zeroed
and missing the negavive values.
Haswell and older use 32-bit deltas so are unaffected by this issue.

v2:
  used int32_t fucntion parameter instead of explicit type conversion.
