cifs: secmech: use shash_desc directly, remove sdesc
The struct sdesc is just a wrapper around shash_desc, with exact same memory layout. Replace the hashing TFMs with shash_desc as it's what's passed to the crypto API anyway. Also remove the crypto_shash pointers as they can be accessed via shash_desc->tfm (and are actually only used in the setkey calls). Adapt cifs_{alloc,free}_hash functions to this change.
