Currently, buffers attached to fastpath CEs are not being allocated
from WBUFF. Since the buffers attached to the fastpath CEs are
re-usable in nature, allocating such buffers from WBUFF will have
added benefits like allocating from custom page frag cache which
reduces the memory used by the RX buffers.
Therefore, allocate RX buffers for fastpath CEs from WBUFF module.
