From: Michal Krawczyk <m...@semihalf.com>
If wrong number of descriptors for refilling was passed to the Rx
repopulate function, there was memory leak which caused memory pool to
run out of resources in longer go.
In case of fail when refilling Rx descriptors, all additional mbufs
have to be released.
