Eric Biggers c5c46887cf crypto: streebog - fix unaligned memory accesses 
Don't cast the data buffer directly to streebog_uint512, as this
violates alignment rules.

Fixes: fe18957e8e ("crypto: streebog - add Streebog hash function")

Eric Biggers 73381da5f9 crypto: streebog - use correct endianness type 
streebog_uint512::qword needs to be __le64, not u64.  This fixes a large
number of sparse warnings:

    crypto/streebog_generic.c:25:9: warning: incorrect type in initializer (different base types)
    crypto/streebog_generic.c:25:9:    expected unsigned long long
    crypto/streebog_generic.c:25:9:    got restricted __le64 [usertype]
    [omitted many similar warnings]

No actual change in behavior.
