[PATCH net-next] nfp: abm: fix error return code in nfp_abm_vnic_alloc()

[Wei Yongjun]

Fix to return negative error code -ENOMEM from the kzalloc() error
handling case instead of 0, as done elsewhere in this function.

Fixes: 174ab544e3bc ("nfp: abm: add cls_u32 offload for simple band 
classification")
