cxgb4: Fix uld_send() for ctrl pkts
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).

DT with the MMU off may result in alignment faults. So fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
