Changed type field to be %x for tree header (line in btrfs_print_tree)

This makes it easier to visually match keys - see:
print-tree.c:btrfs_print_tree():329:

	printf("\tkey %d (%llu %x %llu) block %llu (%llu) gen %llu\n",

I'm not sure if this breaks any other parsers?

[ use %x for key type printks ]

I've gone back and forth on this, since the type used to be a mask. But, right now all the #defines are in decimal, I'd rather keep the output the same way.

Then, perhaps, one should change the %x in
print-tree.c:btrfs_print_tree() to a %u?
