[Qemu-ppc] [QEMU-PPC] [PATCH V2 1/7] target/ppc: Check mask when setting cap_ppc_safe_indirect_branch

[Suraj Jitindar Singh]

Check the character and character_mask field when setting
cap_ppc_safe_indirect_branch based on the hypervisor response
to KVM_PPC_GET_CPU_CHAR. Previously the mask field wasn't checked
which was incorrect.

Fixes: 8acc2ae5 (target/ppc/kvm: Add 
cap_ppc_safe_[cache/bounds_check/indirect_branch])
