net: korina: fix kfree of rx/tx descriptor array
[ Upstream commit 3af5f0f5c74ecbaf757ef06c3f80d56751277637 ]
kmalloc returns KSEG0 addresses so convert back from KSEG1
in kfree. Also make sure array is freed when the driver is
unloaded from the kernel.
Fixes: ef11291bcd5f ("Add support the Korina (IDT RC32434) Ethernet MAC")
