The p->u.board.status is allocated and set a string as
"No" once within allocating a node of BNODE type.
But it also set again with kstrdup() in case of "STATUS"
or "ID". So just free this buffer and allocate again with
kstrdup().

V2: just use kfree for buffers which assigned to newly value
and then allocate again properly.
