Matthias Schiffer ef9d4da6c9 net: eth-uclass: guard against reentrant eth_init()/eth_halt() calls 
With netconsole, any log message can result in an eth_init(), possibly
causing an reentrant call into eth_init() if a driver's ops print
anything:

    eth_init() -> driver.start() -> printf() -> netconsole -> eth_init()
    eth_halt() -> driver.stop() -> printf() -> netconsole -> eth_init()

Rather than expecting every single Ethernet driver to handle this case,
prevent the reentrant calls in eth_init() and eth_halt().

The issue was noticed on an AM62x board, where a bootm after
simultaneous netconsole and TFTP would result in a crash.
