Intel-SIG: commit d0ad4238 dmaengine: idxd: skip irq free when wq type is not kernel.
Incremental backporting patches for DSA/IAA on Intel Xeon platform.

--------------------------------

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().
