Michael S. Tsirkin 322fd48afb e1000: verify we have buffers, upfront 
The spec says: Any descriptor with a non-zero status byte has been
processed by the hardware, and is ready to be handled by the software.

Thus, once we change a descriptor status to non-zero we should
never move the head backwards and try to reuse this
descriptor from hardware.

This actually happened with a multibuffer packet
that arrives when we don't have enough buffers.

Fix by checking that we have enough buffers upfront
so we never need to discard the packet midway through.
