Dan Carpenter c76fa846b0 ath11k: checking for NULL vs IS_ERR() ...

The ath11k_ce_alloc_ring() function returns error pointers on error, not
NULL.  The rest of the driver assumes that "pipe->src_ring" is either
valid or NULL so this patch introduces a temporary varaible to avoid
leaving it as an error pointer.
