cxgb4: Fix queue free path of ULD drivers
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: 94cdb8bb993a (cxgb4: Add support for dynamic allocation
of resources for ULD)
