[PATCH v3 4/7] libfs: Chain encryption checks after case-insensitive revalidation

[Gabriel Krisman Bertazi <krisman@suse.de>]

From: Gabriel Krisman Bertazi <krisman@collabora.com>

Support encrypted dentries in generic_ci_d_revalidate by chaining
fscrypt_d_revalidate at the tail of the d_revalidate.  This allows
filesystem to just call generic_ci_d_revalidate and let it handle any
case-insensitive dentry (encrypted or not).

Signed-off-by: Gabriel Krisman Bertazi <krisman@collabora.com>
