Subject: [PATCH v2 2/2] nvme-auth: set explanation code for failure2 msgs

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.

Signed-off-by: Mark O'Donovan <shiftee@...teo.net>

v1->v2: Set failure explanation in a single place if the error handling
code has not already done so.
