ceph: do not clear I_COMPLETE from d_release
First, this was racy anyway: d_release isn't called until well after the dentry is unhashed. Second, this runs afoul of the recent dcache change that clears d_parent prior to calling d_release (949854d0), causing a NULL pointer dereference. Signed-off-by: Sage Weil <sage@newdream.net>
