Subject: [PATCH] cryptsetup: Treat key file errors as a failed password
 attempt

6f177c7dc092eb68762b4533d41b14244adb2a73 caused key file errors to immediately fail, which would make it hard to correct an issue due to e.g. a crypttab typo or a damaged key file.

Closes #11723.

(cherry picked from commit c20db3887569e0c0d9c0e2845c5286e7edf0133a)
