Prior to this commit, if rte_pktmbuf_alloc_bullk failed during rx queue
setup the error was not returned to the user and they may incorrectly
assume that the rx queue had been successfully set up. This commit ensures
that the error is returned to the user.

Bugzilla ID: 643
Fixes: d8a210774e1d ("net/af_xdp: support unaligned umem chunks")
Cc: stable@dpdk.org
