s3: smbd: Change dptr_closecnum() to use dptr_close() instead of dptr_close_internal().

This will allow us to close any outstanding handles on
an SMB1 connection as later commits move us to using directory
handles instead of pathname directory opens.

This is inefficient, as it means walking the list twice,
but this will only be called with active dptrs in the
OS/2 -1 case, in the connection shutdown case the
directory handles will already have been closed.
