target/ppc/mmu_common: Fix SRR1/MSR error code on Book-E
Book-E architecture does not set the error code in 31:27 bits of SRR1, but instead uses these bits for custom fields such as GS (Guest Supervisor). Wrongly setting these fields will result in QEMU crashes when attempting to execute not executable code due to the attempts to use Guest Supervisor mode.
