[PATCH 02/10] net/mlx5: fix matcher object memory leak

[Itamar Gozlan]

From: Mahmoud Maatuq <mahmoudmatook...@gmail.com>

This makes sure that the allocated matcher object is freed
for all branches that return NULL.

Coverity issue: 426424
Fixes: 27d171b88031 ("net/mlx5: abstract flow action and enable reconfigure")
