vdpa: solidrun: Free IRQs after request failure

Browse Source 
Unwind IRQs already requested by snet_request_irqs() before returning a
VQ IRQ request error so a later DRIVER_OK retry starts from a clean
state. The IRQs are requested and freed while the PCI device remains
bound, so the driver cannot wait for devres cleanup at detach time.

Fixes: 51a8f9d7f5 ("virtio: vdpa: new SolidNET DPU driver.")
