    ve/mm: include virtinfo.h for !CONFIG_BC_IO_ACCOUNTING case
    
    This was found while tring to compile the kernel with a stock
    config (i.e. no CONFIG_BEANCOUNTERS, CONFIG_VE etc.) and
    boot it on IBM Power8.
    
    =============================================================
    
    In case CONFIG_BC_IO_ACCOUNTING is defined, virtinfo.h
    is included via task_io_accounting_ops.h that includes
    bc/io_acct.h that includes virtinfo.h.
    
    In case CONFIG_BC_IO_ACCOUNTING is not defined, we are screwed.
