[PATCH v1] drivers/net: marvell: mvpp2: fix debugfs_create_dir() return check in three functions

[Minjie Du]

Make IS_ERR() judge the debugfs_create_dir() function return
in mvpp2_dbgfs_c2_entry_init(), mvpp2_dbgfs_flow_tbl_entry_init()
 and mvpp2_dbgfs_cls_init()
Line 562 deletes the space because checkpatch reports an error.
