sc: remove antique reference counting hacks from ScDocumentPool

Browse Source 
This attempt to prevent overflowing a 16-bit counter was obsoleted by
the conversion of SfxPoolItem's reference count to ULONG in 2001 or so.

* The sal_uInt16 RefCount can overflow easily for the pattern attributes (SetItems):
* E.g. Alternate formatting for 600 whole cells.
* The RefCount is kept at SC_MAX_POOLREF and not increased/decreased anymore.
* This RefCount is recalculated not until the next load.
* The difference between SC_MAX_POOLREF and SC_SAFE_POOLREF is a little larger than it needs
* to be, to allow for detecting accidental "normal" changes to the RefCount (assertions).
