Subject: [PATCH net-next] bnxt: Don't print message, if DAC isn't connected on both ends

bnxt driver spams logfiles with

[  541.003065] bnxt_en 0000:5d:00.1 eth5: Link speed -1 no longer supported

if a direct attached cable (DAC) is plugged into the bnxt card and is
unplugged on the other side. This patch removes the code printing this
message, since it doesn't provide any useful information.
