[PULL 35/67] target/ppc: use locally stored msr and avoid indirect access |

From: Harsh Prateek Bora <harshpb@linux.ibm.com>
hreg_compute_hflags_value already stores msr locally to be used in most
of the logic in the routine however some instances are still using
env->msr which is unnecessary. Use locally stored value as available.
