Without any uld being loaded, uld_txq_info[] will be NULL. uld_send()
is also used for sending control work requests(for eg: setting filter)
that dont require any ulds to be loaded. Hence move uld_txq_info[]
assignment after ctrl_xmit().
Also added a NULL check for uld_txq_info[].
Fixes: 94cdb8bb993a (cxgb4: Add support for dynamic allocation
of resources for ULD).
