accel: ethosu: Handle possible underflow in IFM size calculations
If the command stream has larger padding sizes than the IFM and OFM
diminsions, then the calculations will underflow to a negative value.
The result is a very large region bounds which is caught on submit, but
it's better to catch it earlier.
Current mesa ethosu driver has a signedness bug which resulted in
padding of 127 (the max) and triggers this issue.
