[Patch] cleanup return values in drivers/misc/sgi-xp

[Dean Nelson <dcn@sgi.com>]

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.
