libceph: don't WARN() if user tries to add invalid key ...
commit b11270853fa3654f08d4a6a03b23ddb220512d8d upstream.
The WARN_ON(!key->len) in set_secret() in net/ceph/crypto.c is hit if a
user tries to add a key of type "ceph" with an invalid payload as
follows (assuming CONFIG_CEPH_LIB=y):
echo -e -n '\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' \
| keyctl padd ceph desc @s
This can be hit by fuzzers. As this is merely bad input and not a
kernel bug, replace the WARN_ON() with return -EINVAL.
Fixes: 7af3ea189a9a ("libceph: stop allocating a new cipher on every crypto request")
