Use the correct function parameter names and add function return
value descriptions to avoid kernel-doc warnings:

Warning: include/linux/siphash.h:82 function parameter 'len' not described
 in 'siphash'
Warning: include/linux/siphash.h:82 No description found for return value
 of 'siphash'
Warning: include/linux/siphash.h:132 function parameter 'len' not
 described in 'hsiphash'
Warning: include/linux/siphash.h:132 No description found for return value
 of 'hsiphash'
