[dpdk-stable] [PATCH 59/67] net/mlx5: fix resource leak in case of error

[Yongseok Koh]

From: Raslan Darawsheh <rasland at mellanox.com>

[ backported from upstream commit 690de2850b26466ad5325fde3e1aff040e3868f8 ]

If something went wrong in mlx5_pci_prob the allocated eth dev
will cause a memory leak.

This commit release the eth dev that was previously allocated.
