Richard Henderson e79b445d89 target/arm: Fix cpu_get_tb_cpu_state() for non-SVE CPUs 
Not only are the sve-related tb_flags fields unused when SVE is
disabled, but not all of the cpu registers are initialized properly
for computing same.  This can corrupt other fields by ORing in -1,
which might result in QEMU crashing.

This bug was not present in 3.0, but this patch is cc'd to
stable because adf92eab90 where the bug was
introduced was marked for stable.

Fixes: adf92eab90
Cc: qemu-stable@nongnu.org (3.0.1)
