net: stmmac: Fix incorrect dereference in interrupt handlers ...
If 'dev' or 'data' is NULL, the 'priv' variable has an incorrect address
when dereferencing calling netdev_err().
Since we get as 'dev_id' or 'data' what was passed as the 'dev' argument
to request_irq() during interrupt initialization (that is, the net_device
and rx/tx queue pointers initialized at the time of the call) and since
there are usually no checks for the 'dev_id' argument in such handlers
in other drivers, remove these checks from the handlers in stmmac driver.
