We need to wait for completion of possible writeback in progress
before we clear on-disk inode during deletion.

simply don't hash the inodes that don't have real inumber instead of
skipping them during iget5_locked(); as the result, simple iget_locked()
would do and we can get rid of cramfs ->drop_inode() as well.

Essentially, the minimal variant of ->evict_inode(). It's
a trimmed-down clear_inode(), sans any fs callbacks. Once
it returns we know that no async writeback will be happening;
every ->evict_inode() instance should do that once and do that
before doing anything ->write_inode() could interfere with
(e.g. freeing the on-disk inode).

All call chains to clear_inode() pass through evict_inode() and
clear_inode() should be called by evict_inode() exactly once.
So we can pull i_bdev/i_cdev detaching up to evict_inode() itself.

Hybrid of ->clear_inode() and ->delete_inode(); if present, does
all fs work to be done when in-core inode is about to be gone,
for whatever reason.
