Subject: vhost_vdpa: unset vq irq before freeing irq
Patch-mainline: v5.15-rc6
Git-commit: 97f854be203883b61d24f230445bd533bbdf770c
References: jsc#PED-1549

Currently we unset vq irq after freeing irq and that will result in
error messages:

  pi_update_irte: failed to update PI IRTE
  irq bypass consumer (token 000000005a07a12b) unregistration fails: -22

This patch solves this.
