Sandipan Das 41d4c889b2 powerpc/sstep: Fix darn emulation 
[ Upstream commit 22b89ba178dd0a66a26699ead014a3e73ff8e044 ]

Commit 8813ff49607e ("powerpc/sstep: Check instruction validity
against ISA version before emulation") introduced a proper way to skip
unknown instructions. This makes sure that the same is used for the
darn instruction when the range selection bits have a reserved value.

Fixes: a23987ef26 ("powerpc: sstep: Add support for darn instruction")
