net: hisilicon: hns: fix error return code of hns_nic_clear_all_rx_fetch()
[ Upstream commit 143c253f42bad20357e7e4432087aca747c43384 ]
When hns_assemble_skb() returns NULL to skb, no error return code of
hns_nic_clear_all_rx_fetch() is assigned.
To fix this bug, ret is assigned with -ENOMEM in this case.
