arm64: module: avoid undefined shift behavior in reloc_data()
Compilers may engage the improbability drive when encountering shifts by a distance that is a multiple of the size of the operand type. Since the required bounds check is very simple here, we can get rid of all the fuzzy masking, shifting and comparing, and use the documented bounds directly.
