Eric Biggers b11270853f libceph: don't WARN() if user tries to add invalid key 
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: 7af3ea189a ("libceph: stop allocating a new cipher on every crypto request")
