This patch introduces a new helper function which can be used both in
lookups and in atomic_open operations by filesystems that want to handle
filename encryption and no-key dentries themselves.
The reason for this function to be used in atomic open is that this
operation can act as a lookup if handed a dentry that is negative. And in
this case we may need to set DCACHE_NOKEY_NAME.

[ebiggers: improved the function comment, and moved the function to just
below __fscrypt_prepare_lookup()]
