dmaengine: idxd: make idxd_wq_enable() return 0 if wq is already enabled

Browse Source 
When calling idxd_wq_enable() and wq is already enabled, code should return 0
and indicate function is successful instead of return error code and fail.
This should also put idxd_wq_enable() in sync with idxd_wq_disable() where
it returns 0 if wq is already disabled.
