[PATCH] crypto: acomp: export all scomp interfaces

[Arnd Bergmann <arnd@arndb.de>]

The newly added scomp/acomp interface has a couple of functions
that should be exported to allow linking the two drivers
as loadable modules:

ERROR: "crypto_acomp_scomp_free_ctx" [crypto/acompress.ko] undefined!
ERROR: "crypto_acomp_scomp_alloc_ctx" [crypto/acompress.ko] undefined!
ERROR: "crypto_init_scomp_ops_async" [crypto/acompress.ko] undefined!

Alternatively, both of them could be combined into one loadable module.

Fixes: 1ab53a77b772 ("crypto: acomp - add driver-side scomp interface")
