Check return value of create_crypto_blk_dev()

cryptfs_enable_internal() forgot to check the return value of
create_crypto_blk_dev(), so it was continuing to
cryptfs_enable_inplace() when creating the dm-crypt device failed, which
doesn't make sense.

Test: see I08fc8465f7962abd698904b5466f3ed080d53953
