s390/cpumf: Fix lpp detection
commit 7a76aa95f6f6682db5629449d763251d1c9f8c4e upstream.
we have to check bit 40 of the facility list before issuing LPP
and not bit 48. Otherwise a guest running on a system with
"The decimal-floating-point zoned-conversion facility" and without
the "The set-program-parameters facility" might crash on an lpp
instruction.
