stm32h7: fix TX timestamp check

It looks like the original code was a bad copy-paste from H5/H7 HALs. ETH_DMATXDESC_LS and ETH_DMATXDESC_TTSS are flags from the DuESC0 register. This fix allows to effectively set the TX timestamp properly when there is one. Signed-off-by: Benjamin Cabé <[email protected]>
