Fix compiler warning for variable 'blk' set but not used in
xfs_attr_node_removename_setup. blk is used only in an ASSERT so only
declare blk when DEBUG is set.

But now a non-DEBUG compilation will trip over the assignment to blk:
blk = &(*state)->path.blk[(*state)->path.active - 1];
that comes just before the asserts, right?
ASSERT((*state)->path.blk[(*state)->path.active - 1].bp != NULL);
ASSERT((*state)->path.blk[(*state)->path.active - 1].magic ==
XFS_ATTR_LEAF_MAGIC);
In the end you probably just want to encode the accessor logic in the
assert body so the whole thing just disappears entirely.
Alrighty, will fix
