Subject: nfp: abm: fix error return code in nfp_abm_vnic_alloc()
Git-commit: 5099dea0a59f1c89525bb0ceac36689178a4c125
Patch-mainline: 5.7-rc6
References: networking-stable-20_05_16

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")
