[PATCH 12/16] target/arm/hvf: Move flush_cpu_state() into the inner vCPU loop

To ensure the vCPU state is flushed on each inner loop iteration,
move the flush_cpu_state() inside it, right after the interrupt
injection check (catching any interrupt changes from previous loop).

Since flush_cpu_state() uses CPUState::vcpu_dirty field as a lazy
synchronization mechanism, there is no performance penalty if the
cache is clean.

This got missed while refactoring the inner loop in commit 93ac76507.

Fixes: 93ac765076a ("target/arm/hvf: Keep calling hv_vcpu_run() in loop")
