[dts] [PATCH] framework/crb: Throwing exception in case requested core configuration cannot be fulfilled

[Radoslaw Biernacki <radoslaw.biernacki@linaro.org>]

Throwing exception instead of returning empty core set cause proper
error handling. Returning empty core set cause invalid parameter being
passed to EAL which in turn cause early exit from test program.
