Reword an incorrect error message

This change rewords the error message that is emitted if the lock
command fails. The old message was incorrectly stating a problem with
the retrieval of the device's status.
While at it, also slightly rephrase the description for the hidden
command to be more in line with that of the other storage commands, and
replace lowercase 'nitrokey' with a capitalized one in a few comments.
