EmbeddedPkg/Lan9118Dxe: Fix the reset after a receiver or transmitter error

The Lan9118 driver did not recover after a receiver error as the error
handling code stopped the transmitter but did not restart it. Added the
restart of the transmitter.

Added also the restart of the receiver after a transmitter error and
the reactivation of the LEDs after all resets.
