drivers/misc/sgi-xp: clean up return values

Make XP return values more generic to XP and not so tied to XPC by changing
enum xpc_retval to xp_retval, along with changing return value prefixes from
xpc to xp.  Also, cleanup a comment block that referenced some of these return
values as well as the handling of BTE related return values.
