[libvirt] [PATCH v3 4/8] vsh: Extract vshCmddefCheckInternals from vshCmddefOptParse
Originally introduced by commit 2432521e which correctly split
vshCmddefOptParse into command's options validation and options parsing.
However, command's 'internals' are not tied solely to .options, rather it
should be about the overall structure, therefore the validation should be
extracted from vshCmddefOptParse and performed before any attempt to parse the
command's options.
