Dave Jiang 50e7e7f6f2 dmaengine: idxd: wq size configuration needs to check global max size 
The current size_store() function for idxd sysfs does not check the total
wq size. This allows configuration of all wqs with total wq size. Add check
to make sure the wq sysfs attribute rejects storing of size over the total
wq size.

Fixes: c52ca47823 ("dmaengine: idxd: add configuration component of driver")
