dsa: mv88e6xxx: fix debug print for SPEED_UNFORCED
[ Upstream commit e08cdf63049b711099efff0811273449083bb958 ]
Debug print uses invalid check to detect if speed is unforced:
(speed != SPEED_UNFORCED) should be used instead of (!speed).
Found by Linux Verification Center (linuxtesting.org) with SVACE.
