[PATCH net] net: stmmac: Fix EST offset for dwmac 5.10

Fix EST offset for dwmac 5.10.

Currently configuring Qbv doesn't work as expected. The schedule is
configured, but never confirmed:

|[ 128.250219] imx-dwmac 428a0000.ethernet eth1: configured EST

The reason seems to be the refactoring of the EST code which set the wrong
EST offset for the dwmac 5.10. After fixing this it works as before:

|[ 106.359577] imx-dwmac 428a0000.ethernet eth1: configured EST
|[ 128.430715] imx-dwmac 428a0000.ethernet eth1: EST: SWOL has been switched

Tested on imx93.
