untangle fsnotify_d_instantiate() a bit
First of all, don't bother calling it if inode is NULL - that makes inode argument unused. Moreover, do it *before* dropping ->d_lock, not right after that (and don't bother grabbing ->d_lock in it, of course). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
