net: stmmac: selftests: Always use max DMA size in Jumbo Test 

Although some XGMAC setups support frames larger than DMA size, some of
them may not. As we can't know before-hand which ones support let's use
the maximum DMA buffer size in the Jumbo Tests.

User can always reconfigure the MTU to achieve larger frames.
