commit aa326fb8f87fa0e2db6901db2ccb93cd582dd44f

knet: pass correct handle to knet_handle_compress
totemknet_configure_compression was using knet_context
just to gather the knet handle / instance.
On first time config knet_contex is not initialized till
much later in the code, passing some random garbage pointers
to knet_handle_compress, that would crash later trying
to acquire a mutex lock.
