gianfar: Fix Rx/Tx HW interrupt coalescing counter reset procedure.
- Fix Rx/Tx HW interrupt coalescing counter reset logic. Disabling is required before resetting the counter. - Update the Default both Rx and Tx coalescing timer threshold. Formerly 4 is set which is equal to 1.5 frame at the line rate of 1GbE interface, and it doesn't match to the coalescing frame count which is set to 16. Threashold 21 is matched to frame count 16.
