ethernet: atl1: Add missing DMA mapping error checks and count errors
The `dma_map_XXX()` functions can fail and must be checked using
`dma_mapping_error()`. This patch adds proper error handling for all
DMA mapping calls.
In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is
deallocated and marked accordingly.
In `atl1_tx_map()`, previously mapped buffers are unmapped and the
packet is dropped on failure.
If `atl1_xmit_frame()` drops the packet, increment the tx_error counter.
Fixes: f3cc28c79760 ("Add Attansic L1 ethernet driver.")
