[PATCH AUTOSEL 4.19 39/43] nfp: flower: fix memory leak in nfp_flower_spawn_vnic_reprs

[Sasha Levin]

From: Navid Emamdoost <navid.emamdo...@gmail.com>

[ Upstream commit 8ce39eb5a67aee25d9f05b40b673c95b23502e3e ]

In nfp_flower_spawn_vnic_reprs in the loop if initialization or the
allocations fail memory is leaked. Appropriate releases are added.

Fixes: b94524529741 ("nfp: flower: add per repr private data for LAG offload")
