pipewire: introspect: do not leave spa_param_infos uninitialized

Browse source 
`pw_reallocarray()` leaves the newly allocated storage (if any)
uninitialized, so fill the bytes of the new `spa_param_info` objects
with zeros in `pw_{node,port,device}_info_merge()` to avoid handing
out pointers to uninitialized storage.
