[ Upstream commit 16736e11f43b80a38f98f6add54fab3b8c297df3 ]

The TLS TIS object contains the dek/key ID.
By destroying the key first, the TIS would contain an invalid
non-existing key ID.
Reverse the destroy order, this also acheives the desired assymetry
between the destroy and the create flows.

Fixes: d2ead1f360e8 ("net/mlx5e: Add kTLS TX HW offload support")
