Vitaliy Shevtsov c60af16e1d nvmet-auth: assign dh_key to NULL after kfree_sensitive 
[ Upstream commit d2f551b1f7 ]

ctrl->dh_key might be used across multiple calls to nvmet_setup_dhgroup()
for the same controller. So it's better to nullify it after release on
error path in order to avoid double free later in nvmet_destroy_auth().

Found by Linux Verification Center (linuxtesting.org) with Svace.
