[PATCH v2] net: stmmac: compare p->des0 and p->des1 with __le32 type values

[Min-Hua Chen]

Use cpu_to_le32 to convert the constants to __le32 type
before comparing them with p->des0 and p->des1 (they are __le32 type)
and to fix following sparse warnings:

drivers/net/ethernet/stmicro/stmmac/dwxgmac2_descs.c:110:23: sparse: warning: restricted __le32 degrades to integer
drivers/net/ethernet/stmicro/stmmac/dwxgmac2_descs.c:110:50: sparse: warning: restricted __le32 degrades to integer
