net: ethernet: adi: adin1110: Fix uninitialized variable

Browse source 
[ Upstream commit 965f9b8c0c1b37fa2a0e3ef56e40d5666d4cbb5c ]

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.
