ethernet: enlarge ethernet task stack size

1. In original driver, the stack size for emac driver task "emacT" is only 2048 Bytes, which also can not be changed by user.
2. Each time when invoking "emac_start" function, it will reset emac registers, the driver should reconfig some important registers again.

Closes https://github.com/espressif/esp-idf/issues/3025
