Cleanup: Fix for/else with no break in AddAuthorizedKeys
Cleanup: Fix for/else with no break in AddAuthorizedKeys

After a refactoring in c178396, the only break statement in the for/else
loop in AddAuthorizedKeys was removed. This means the else block is
always executed, so remove the else: to quell a pylint warning.

No functional change.
