cifs: use get/put_unaligned functions to access ByteCount
It's possible that when we access the ByteCount that the alignment will be off. Most CPUs deal with that transparently, but there's usually some performance impact. Some CPUs raise an exception on unaligned accesses. Fix this by accessing the byte count using the get_unaligned and put_unaligned inlined functions. While we're at it, fix the types of some of the variables that end up getting returns from these functions.
