use ->d_seq to get coherency between ->d_inode and ->d_flags

commit a528aca7f359f4b0b1d72ae406097e491a5ba9ea upstream.

Games with ordering and barriers are way too brittle.  Just
bump ->d_seq before and after updating ->d_inode and ->d_flags
type bits, so that verifying ->d_seq would guarantee they are
coherent.
