Fenghua Yu 863676fe1a dmaengine: idxd: Clear PRS disable flag when disabling IDXD device 
Disabling IDXD device doesn't reset Page Request Service (PRS)
disable flag to its initial value 0. This may cause user confusion
because once PRS is disabled user will see PRS still remains the
previous setting (i.e. disabled) via sysfs interface even after the
device is disabled.

To eliminate user confusion, reset PRS disable flag to ensure that
the PRS flag bit reflects correct state after the device is disabled.

Additionally, simplify the code by setting wq->flags to 0, which clears
all flag bits, including any future additions.
