Description: Fix for failing float/double variadic args test cases in ruby-ffi package
 This patch will fix the problem of passing float/double values as part of variadic 
 argument list from ruby-ffi package. All the test cases related to float/double arguments
 passed as part of ruby variadic list were failing on ppc64le arch. Problem was due to 
 incorrect way to call C method ffi_prep_cif_var, where third argument was passed as total 
 number of arguments instead of fixed number of arguments
