fix err/req irq fd issue #731

Closed limiao-intel closed 1 year ago

limiao-intel commented 1 year ago

When handle_device_set_irqs set err irq/req irq, fd will be filled in vfu_ctx->irqs->efds[] rather than vfu_ctx->irqs->err_efd/vfu_ctx->irqs->req_efd. So, err/req irq fd will be mistakenly used as msi/x irq fd, which will cause program stuck.
