1. use pointer rather than pointer's pointer for acomp_ctx;
2. fix the race while multiple zpool exist while dynamically switching

users may call crypto_has_acomp to confirm the existence of acomp before using
crypto_acomp APIs. Right now, many acomp have scomp backend, for example, lz4,
lzo, deflate etc. crypto_has_acomp will return false for them even though they
support acomp APIs.

true for them is calling this APIs like
crypto_has_acomp("xxx", CRYPTO_ALG_TYPE_SCOMPRESS, 0);
But it looks quite weird.
