s390x: Rename and use constants for short PSW address and mask

Let's rename PSW_MASK_ESA_ADDR to PSW_MASK_SHORT_ADDR because we're
not working with a ESA PSW which would not support the extended
addressing bit. Also let's actually use it.

Additionally we introduce PSW_MASK_SHORT_CTRL and use it throughout
the codebase.
