previously, we want to regard the two mdevs created with dsa-1dwq x

dsa-2dwq x 15 as compatible, because the two mdevs consist equal resources.
But, as it's a burden to upper layer, we agree that if this condition
happens, we still treat the two as incompatible.
To fix it, either the driver should expose dsa-1dwq only, or the target
dsa-2dwq needs to be destroyed and reallocated via dsa-1dwq x 30.
AFAIU, these are mdev types, aren't they? So, basically, any management
software needs to take care to use the matching mdev type on the target
system for device creation?
