swiotlb: fix passing local variable to debugfs_create_ulong()
Debugfs node will be run-timely checked and so local variable
should be not passed to debugfs_create_ulong(). Fix it via
debugfs_create_file() to create io_tlb_used node and calculate
used io tlb number with fops_io_tlb_used attribute.
Fixes: 20347fca71a3 ("swiotlb: split up the global swiotlb lock")
