net: mvneta: fix use of state->speed
[ Upstream commit5.4-rM2-2.2.x-imx-squashedf2ca673d2c
] When support for short preambles was added, it incorrectly keyed its decision off state->speed instead of state->interface. state->speed is not guaranteed to be correct for in-band modes, which can lead to short preambles being unexpectedly disabled. Fix this by keying off the interface mode, which is the only way that mvneta can operate at 2.5Gbps. Fixes:da58a931f2
