* Added logic to check for the supported line width range before setting the line width to avoid errors.
I also moved the glLineWidth call so that it could be after the call to get the supported line width range for the desired line type.
* Moved the glLineWidth call outside the if/else
* Moved the code to query line GL_SMOOTH_LINE_WIDTH_RANGE and GL_ALIASED_LINE_WIDTH_RANGE to nv2a_gl_context_init(void) so that it's just called while OpenGL is being initialized.
* Removed the lineWidth local variable. It's simpler to just call glLineWidth in the if and else blocks
When vfio_enable_vectors() returns with less than requested nr_vectors
we retry with what kernel reported back. But the retry path doesn't
call vfio_prepare_kvm_msi_virq_batch() and this results in,
qemu-system-aarch64: vfio: Error: Failed to enable 4 MSI vectors, retry with 1
qemu-system-aarch64: ../hw/vfio/pci.c:602: vfio_commit_kvm_msi_virq_batch: Assertion `vdev->defer_kvm_irq_routing' failed

The kvm irqchip notifier is only registered if the device supports
INTx, however it's unconditionally removed in vfio realize error
path. If the assigned device does not support INTx, this will cause
QEMU to crash when vfio realize fails. Change it to conditionally
remove the notifier only if the notify hook is setup.
Before fix:
(qemu) device_add vfio-pci,host=81:11.1,id=vfio1,bus=root1,xres=1
Connection closed by foreign host.
After fix:
(qemu) device_add vfio-pci,host=81:11.1,id=vfio1,bus=root1,xres=1
Error: vfio 0000:81:11.1: xres and yres properties require display=on
(qemu)
