swiotlb: fix debugfs reporting of reserved memory pools

Browse source

[ Upstream commit 5499d01c02 ]

For io_tlb_nslabs, the debugfs code reports the correct value for a
specific reserved memory pool.  But for io_tlb_used, the value reported
is always for the default pool, not the specific reserved pool. Fix this.
