Remove zpl_revalidate
This patch removes the need for zpl_revalidate altogether. There were 3 main reasons why we used d_revalidate: 1. periodic automounted snapshots umount deferral 2. negative dentries created before snapshot rollback 3. stale inodes referenced by dentry cache after snapshot rollback Periodic snapshots deferral solution introduces zfs_exit_fs function, which is called as a part of ZFS_EXIT(zfsvfs_t) macro. Negative dentries and stale inodes are solved by flushing the dcache for the particular dataset on zfs_resume_fs call. This patch also removes now unused HAVE_S_D_OP configure test.
