crypto: aesni - Fix failure when pcbc module is absent
When aesni is built as a module together with pcbc, the pcbc module must be present for aesni to load. However, the pcbc module may not be present for reasons such as its absence on initramfs. This patch allows the aesni to function even if the pcbc module is enabled but not present. Reported-by: Arkadiusz Miƛkiewicz <arekm@maven.pl> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
