dmaengine: idxd: skip irq free when wq type is not kernel
Skip wq irq resources freeing when wq type is not kernel since the driver
skips the irq alloction during wq enable. Add check in wq type check in
idxd_wq_free_irq() to mirror idxd_wq_request_irq().
Fixes: 63c14ae6c161 ("dmaengine: idxd: refactor wq driver enable/disable operations")
