Do not complain when /dev/crypto does not exist. 



FreeBSD does not enable cryptodev(4) by default.  OpenBSD disabled support
for /dev/crypto by default from 4.9 and removed it from 5.7.  Now the engine
is properly enabled by default on BSD platforms (see #7885), it continuously
complains:

Could not open /dev/crypto: No such file or directory

Hide the nagging error message behind ENGINE_DEVCRYPTO_DEBUG.
