[dpdk-dev] [PATCH] vhost: change mbuf allocation logs to debug

[Allain Legacy <allain.legacy@windriver.com>]

From: Matt Peters <matt.peters@windriver.com>

The current packet buffer alloc failures of the vhost dequeue operations
can flood the log system with error logs due to logging a runtime error
condition within the data path.  In order to prevent this condition, but
still enable debugging, the logs are being changed to debug logs to ensure
they are not emitted unless the CONFIG_RTE_LIBRTE_VHOST_DEBUG option is
enabled.
