QHeaderView - remove sectionCount variable

Browse Source 
A previous patch ensures that we have exactly one section in a Span.
( see SHA : b800d8b94a7861ecf8853621f6556fca186fb5b7 )

Therefore we no longer need the sectionCount variable. We have
assess to it through the sectionSpan.count.  To keep this patch
quite simple the variable sectionCount has been changed to a
function returning the count value.
