====================
net: macb: fix the link speed the taprio setup reads

Two small fixes in macb_taprio_setup_replace(), both in how it obtains
the link speed it scales the schedule with.

The first: it hands phylink_ethtool_ksettings_get() a stack variable
it never zeroed, while phylink fills only what the link mode provides
and even reads one field back from the caller. The second: the speed
check is written as "<= 0" on a u32, so SPEED_UNKNOWN passes it and
turns into a 1 ns hardware limit that every entry then exceeds.

Compile-tested against net; the driver has no test surface, and no
macb board here.
