replace d_add_unique() with saner primitive
new primitive: d_exact_alias(dentry, inode). If there is an unhashed dentry with the same name/parent and given inode, rehash, grab and return it. Otherwise, return NULL. The only caller of d_add_unique() switched to d_exact_alias() + d_splice_alias(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
