vsh: vshCmddefHelp: Drop the unnecessary 'else' branch
If the initial check is true the function immediately returns so there's no need to enclose the code following the check within an 'else' block. Also, by removing the 'else' block, the declarations need to be moved to beginning of the function block to conform with our guidelines. Signed-off-by: Erik Skultety <eskultet@redhat.com>
