Thomas Fourier 715f6dbe9b ethernet: ionic: Fix DMA mapping tests ...

[ Upstream commit d5e3241c5a ]

Change error values of `ionic_tx_map_single()` and `ionic_tx_map_frag()`
from 0 to `DMA_MAPPING_ERROR` to prevent collision with 0 as a valid
address.

This also fixes the use of `dma_mapping_error()` to test against 0 in
`ionic_xdp_post_frame()`

Fixes: 0f3154e6bc ("ionic: Add Tx and Rx handling")
Fixes: 56e41ee12d ("ionic: better dma-map error handling")
Fixes: ac8813c0ab ("ionic: convert Rx queue buffers to use page_pool")
