GRETH: Moved print to remove potential deadlock

Deadlock may arise when the EDCL bug link is used to tunnel
console output over Ethernet, when Ethernet is down one should
avoid using console (only during debugging of LEON targets)

GRETH: performance improvements and one bugfix

GRETH driver updated, 10-15% performance improvements for GBIT MAC,
unnecessary RX interrupts not taken which under heavy load saves approx.
1500 interrupts/s, one task removed saving about 5kb memory and 1 bug
solved.

BUG: RX interrupt was enabled before the RX-daemon was created which could
result in a faulty call to rtems_event_send.
