Subject: [PATCH AUTOSEL 6.6 15/40] nvme-auth: set explanation code for failure2 msgs

From: Mark O'Donovan <shiftee@...teo.net>

[ Upstream commit 38ce1570e2c46e7e9af983aa337edd7e43723aa2 ]

Some error cases were not setting an auth-failure-reason-code-explanation.
This means an AUTH_Failure2 message will be sent with an explanation value
of 0 which is a reserved value.
