memory leak with RCU_TABLE_FREE
commit e73b7fffe487c315fd1a4fa22282e3362b440a06 upstream.
The rcu page table free code uses a couple of bits in the page table
pointer passed to tlb_remove_table to discern the different page table
types. __tlb_remove_table extracts the type with an incorrect mask which
leads to memory leaks. The correct mask is ((FRAG_MASK << 4) | FRAG_MASK).
