[PATCH] Fix cppcheck "possible null dereference" in ScMyCellInfo::CreateCell.

It's safe to remove the check since CreateCell is only called by
CreateContentAction, CreateGeneratedActions and SetDependencies in the
same file and those in turn are only called by CreateChangeTrack only
if pDoc is not NULL.
