dmaengine: idxd: Fix issues with PRS disable sysfs knob
There are two issues in the current PRS disable sysfs store function
wq_prs_disable_store():
1. Since PRS disable knob is invisible if PRS disable is not supported
in WQ, it's redundant to check PRS support again in the store function
again. Remove the redundant PRS support check.
2. Since PRS disable is read-only when the device is not configurable,
PRS disable cannot be changed on the device. Add device configurable
check in the store function.
Fixes: f2dc327131b5 ("dmaengine: idxd: add per wq PRS disable")
