[Devel] do_assign: no value in right expression

[Daniel-Constantin Mierla]

Hello,

assuming NULL value can producing unexpecting results. For example, 
assigning null to an avp will delete first avp with that name. It might 
not be what exactly someone expects from such operation -- instead of 
getting a new avp, you get deleted an existing one.

Cheers,
Daniel
