stm32f4/f7/h7_eth: Improvements in Ethernet DMA error handling.

Browse Source 
* Error handling for abnormal interrupts and DMA errors is now
enabled for all builds, regardless of any DEBUG configuration.

* Error handling resets the MAC for the specific errors that
may halt the Ethernet operation, instead of everything as it
was before.
