! Purpose: deallocate memory for variables associated with buffer datastructure 
!          for all active regions on current processor.
!
! Description: none.
!
! Input: regions   = all regions
!        iReg      = region number.
!
! Output: region%levels%patch%buffPlag = Buffplag variables
!
! Notes: none.
