Subject: [PATCH] mempool/dpaa2: fix error code for allocation failure

[ upstream commit 6ed4390e5e16ddc836279946591618527cd69544 ]

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.
