[PATCH] dmaengine: idxd: match type for retries var in idxd_enqcmds()

[Dave Jiang <dave.jiang@xxxxxxxxx>]

wq->enqcmds_retries is defined as unsigned int. However, retries on the
stack is defined as int. Change retries to unsigned int to compare the same
type.

Fixes: 7930d8553575 ("dmaengine: idxd: add knob for enqcmds retries")
