[net] net: ethernet: adi: adin1110: Fix uninitialized variable

[Ciprian Regus]

From: Dell Jin <dell.jin.code@xxxxxxxxxxx>

The spi_transfer struct has to have all it's fields initialized to 0 in
this case, since not all of them are set before starting the transfer.
Otherwise, spi_sync_transfer() will sometimes return an error.

Fixes: a526a3cc9c8d ("net: ethernet: adi: adin1110: Fix SPI transfers")
