parisc: Fix get_user() for 64-bit value on 32-bit kernel

commit 3f795cef0ecdf9bc980dd058d49bdab4b19af1d3 upstream.

This fixes a bug in which the upper 32-bits of a 64-bit value which is
read by get_user() was lost on a 32-bit kernel.
While touching this code, split out pre-loading of %sr2 space register
and clean up code indent.
