Subject: net/mlx5: fix memory leak on context allocation failure
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c76db6a4964e91a79d877a009d15d5c62507136a;p=dpdk.git

net/mlx5: fix memory leak on context allocation failure

In shared device context creation, there is a missing validation when
one of the btree memory allocation fails that will cause a memory leak.

This adds a proper check to clean resources in case of failure.
