net: stmmac: Use bfsize1 in ndesc_init_rx_desc
gcc warn this:
drivers/net/ethernet/stmicro/stmmac/norm_desc.c: In function ndesc_init_rx_desc:
drivers/net/ethernet/stmicro/stmmac/norm_desc.c:138:6: warning: variable 'bfsize1' set but not used [-Wunused-but-set-variable]
Like enh_desc_init_rx_desc, we should use bfsize1
in ndesc_init_rx_desc to calculate 'p->des1'
Fixes: 583e63614149 ("net: stmmac: use correct DMA buffer size in the RX descriptor")
