cxgb4: Fix queue free path of ULD drivers



[ Upstream commit d7cb44496a9bb458632cb3c18acb08949c210448 ]

Setting sge_uld_rxq_info to NULL in free_queues_uld().
We are referencing sge_uld_rxq_info in cxgb_up(). This
will fix a panic when interface is brought up after a
ULDq creation failure.

Fixes: 94cdb8bb (cxgb4: Add support for dynamic allocation
       of resources for ULD)
