net/mlx5e: Use rx_missed_errors instead of rx_dropped for reporting buffer exhaustion

[ Upstream commit 5c74195d5dd977e97556e6fa76909b831c241230 ]

Previously, the driver incorrectly used rx_dropped to report device
buffer exhaustion.

According to the documentation, rx_dropped should not be used to count
packets dropped due to buffer exhaustion, which is the purpose of
rx_missed_errors.

Use rx_missed_errors as intended for counting packets dropped due to
buffer exhaustion.
