IPSEC uses block ciphers asynchronous, but probes only for synchronous block
ciphers and makes ealg entries only available if synchronous block cipher is
found. So with setup, where hardware crypto driver registers asynchronous
block ciphers and software crypto module is not build, ealg is not marked
as being available.

Use crypto_has_ablkcipher instead and remove ASYNC mask.
