octeontx2-af: Fix initialization of mcam's entry2target_pffunc field

NPC mcam entry stores a mapping between mcam entry and target pcifunc.
During initialization of this field, API kmalloc_array has been used which
caused some junk values to array. Whereas, the array is expected to be
initialized by 0. This patch fixes the same by using kcalloc instead of
kmalloc_array.
