[dpdk-dev] [PATCH v2 1/2] mempool/dpaa2: fix the return value for alloc fail

[Hemant Agrawal]

In case the alloc api is not able to allocate the required
number of buffer, it can return '0', which will not indicate
the failure to the calling function.
This patch fix the return value to indicate the failure.
