shmem: no dentry retention past the refcount reaching zero

Just set DCACHE_DONTCACHE in ->s_d_flags and be done with that.
Dentries there live for as long as they are pinned; once the
refcount hits zero, that's it.  The same, of course, goes for
other tree-in-dcache filesystems - more in the next commits...
