COMPMID-1156: Allow memory reusage when trying to reallocate a smaller CLTensor
In case of reconfiguration there might be the need for reallocating internal
data. This patch allows resusage of already allocated memory for CLTensors only
if the newly requested memory is smaller than the previous one, otherwise an
error is thrown.
