[PATCH] nfp: abm: fix a memory leak bug

[wu000273]

From: Qiushi Wu <wu000...@umn.edu>

In function nfp_abm_vnic_set_mac, pointer nsp is allocated by nfp_nsp_open.
But when nfp_nsp_has_hwinfo_lookup fail, the pointer is not released,
which can lead to a memory leak bug. Fix this issue by adding
nfp_nsp_close(nsp) in the error path.
