David Gibson efb7db250a target/ppc: Fix backwards migration of msr_mask
21b786f "PowerPC: Add TS bits into msr_mask" added the transaction states
to msr_mask for recent POWER CPUs to allow correct migration of machines
that are in certain interim transactional memory states.

This was correct, but unfortunately breaks backwards of pseries-2.7 and
earlier machine types which (stupidly) transferred the msr_mask in the
migration stream and failed if it wasn't equal on each end.

This works around the problem by masking out the new MSR bits in the
compatibility code to send the msr_mask on old machine types.
