raw/ifpga: fix free function mismatch in interrupt config

The raw ifpga driver redefines malloc to be opae_malloc
and free to be opae_free; which is a bad idea.

This leads to case where interrupt efd array is allocated with calloc()
and then passed to rte_free.
The workaround is to allocate the array with rte_calloc() instead.

Fixes: d61138d ("drivers: remove direct access to interrupt handle")
