Commit 0307afc681 ("networkctl: add support to display Transmit/Recieve queue
length (#12633)") added the display of the number of RX and TX Queues to the
output of `networkctl status $DEV`. However the row description says "Queue
Length".
This patch fixes the output by replacing "Queue Length" by "Number of Queues".
