cifs: add new function to get unicode string length in bytes
Working in units of words means we do a lot of unnecessary conversion back and forth. Standardize on bytes instead since that's more useful for allocating buffers and such. Also, remove hostlen_fromUCS since the new function has a similar purpose.
