net: spacemit: Fix error handling in emac_alloc_rx_desc_buffers()

Browse source

[ Upstream commit 3aa1417803 ]

Even if we get a dma_mapping_error() while mapping an RX buffer, we
should still update rx_ring->head to ensure that the buffers we were
able to allocate and map are used. Fix this by breaking out to the
existing code after the loop, analogous to the existing handling for skb
allocation failure.
