With support for segmented packets, it is now possible to easily receive
packets of many sizes, given an adequate number of descriptors.

Remove limitation on the minimum size of mbuf: on reception, if a packet
won't fit in the queue's mbufs, it will be detected in the packet info
and the packet will be discarded.

Fixes: 4a6bb33dc67c ("net/tap: support segmented mbufs")
