[PATCH] ceph: fix compilation error when building kernel without FS_ENCRYPT

[PATCH] ceph: fix compilation error when building kernel without FS_ENCRYPT

[Luís Henriques]

When compiling without FS_ENCRYPTION config, the kernel will fail to build
with:

fs/ceph/inode.c:196:7: error: no member named 'fscrypt_auth' in 'struct ceph_inode_info'

Enclose the code within an #ifdef CONFIG_FS_ENCRYPTION to fix it.

Jeff, feel free to squash this patch into one of the previous patches from
the snapshot names encryption series.

Thanks, I folded this one into this patch:

    ceph: add support for encrypted snapshot names
