net: arc_emac: fix arc_emac_rx() error paths
[ Upstream commit e688822d035b494071ecbadcccbd6f3325fb0f59 ]
arc_emac_rx() has some issues found by code review.
In case netdev_alloc_skb_ip_align() or dma_map_single() failure
rx fifo entry will not be returned to EMAC.
In case dma_map_single() failure previously allocated skb became
lost to driver. At the same time address of newly allocated skb
will not be provided to EMAC.
