A single character type resulted in way fewer TX descriptors being
available than allocated. Not only resulted this in wasting memory,
but also when more iolist chunks than descriptors are send, the
```C
assert(iolist_count(iolist) <= ETH_TX_DESCRIPTOR_COUNT);
```
does not trigger. As a result, old TX descriptors are being overwritten
in this case.
(cherry picked from commit 82fbe08)

Testing procedure
@fabian18 has a test that reliably triggers the bug. He should be able to confirm it is gone now. But actually, it should be pretty obvious from the code that this fixes a typo.
