net/rocker: Remove the dead error handling

Browse source 
Memory allocation functions like world_alloc, desc_ring_alloc etc,
they are all wrappers around g_malloc, g_new etc. But g_malloc and
similar functions doesn't return null. Because they ignore the fact
that g_malloc() of 0 bytes returns null. So error checks for these
allocation failure are superfluous. Now, remove them entirely.
