net: atlantic: fix potential error handling
commit 380ec5b9af7f0d57dbf6ac067fd9f33cff2fef71 upstream.
Code inspection found that in case of mapping error we do return current
'ret' value. But beside error, it is used to count number of descriptors
allocated for the packet. In that case map_skb function could return '1'.
Changing it to return zero (number of mapped descriptors for skb)
