lib/swiotlb.c: Fix strange panic message selection logic when swiotlb fills up
swiotlb_full() in lib/swiotlb.c throws one of two panic messages
based on whether the direction of transfer is from the device
or to the device. The logic around this is somewhat weird in
the case of bidirectional transfers. It appears to want to
throw both in succession, but since its a panic only the first
makes it.
This patch adds a third, separate error for DMA_BIDIRECTIONAL
to make things a bit clearer.
