bug#10388: Assoc list confusion in set-procedure-properties!

[Mike Gran]

Hi-
 
In Guile 2.0.2, scm_set_procedure_properties (when SCM_ENABLE_DEPRECATED)
has a call to scm_assq where the KEY and ALIST parameters are reversed.
 
To demonstrate, try this
> (define (func x) #t)
> (set-procedure-properties! func (procedure-properties func))
 
ERROR: In procedure assq: Wrong type argument in position 2
(expecting association list): arity
 
Thanks,
 
Mike Gran
