    ar71xx: Fix mikrotik NAND compile problem
    
    This fixes the following compile error:
    drivers/mtd/nand/rb91x_nand.c: In function 'rb91x_nand_remove':
    drivers/mtd/nand/rb91x_nand.c:445:16: error: 'rbni' undeclared (first use in this function)
      nand_release(&rbni->chip);
    
    Fixes: 0f07496f520c ("kernel: Update kernel 4.9 to version 4.9.229")
    Signed-off-by: Hauke Mehrtens <hauke at hauke-m.de>
