Subject: ncpfs: fix a braino in OOM handling in ncp_fill_cache()

From: Al Viro <[email protected]>

commit 803c00123a8012b3a283c0530910653973ef6d8f upstream.

Failing to allocate an inode for child means that cache for *parent* is incompletely populated. So it's parent directory inode ('dir') that needs NCPI_DIR_CACHE flag removed, *not* the child inode ('inode', which is what we'd failed to allocate in the first place).

Fucked-up-in: commit 5e993e25 ("ncpfs: get rid of d_validate() nonsense")
