Dawid Gorecki 9ae7a13f82 net/ena: check memory BAR before initializing LLQ 
The ena_com_config_dev_mode() performs many calculations related to LLQ
and then performs an admin queue call to configure LLQ in the device.

All of the operations performed by ena_com_config_dev_mode() are
unnecessary if membar hasn't been found. Move the dev_mem_base check
before ena_com_config_dev_mode() call. This prevents the unnecessary
operations from being performed.
