target/s390x: improve 24-bit and 31-bit addresses read
Improve fix_address to also handle the 24-bit mode. Rename fix_address to wrap_address to better explain what is changed. Replace the calls to get_address with x2 = 0 and b2 = 0 by call to wrap_address, leading to the removal of this function. Rename get_address_31fix into get_address.
