net/cnxk: fix default MCAM allocation size

Preallocation of MCAM entries is not valid anymore since the
AF side MCAM allocation scheme has changed. This patch disables
preallocation by changing the default MCAM preallocation size
from 8 to 1.

Fixes: 168c59cfe42 ("net/octeontx2: add flow MCAM utility functions")
