net: stmmac: rearrange tc_init()

Browse Source 
To make future changes easier, rearrange the use of dma_cap->l3l4fnum
vs priv->flow_entries_max.

Always initialise priv->flow_entries_max from dma_cap->l3l4fnum, then
use priv->flow_entries_max to determine whether we allocate
priv->flow_entries and set it up.

This change is safe because tc_init() is only called once from
stmmac_dvr_probe().
