[PATCH] scsi: qedi: qedi_main.c: modify the code flow in 'qedi_alloc_global_queues'

[Peizhi Li]

When goto the mem_alloc_failure, it will result in a null pointer 
reference to variable 'gl' in function 'qedi_free_global_queues', 
due to the 'qedi->global_queues' not being allocated.

Fix this by returning -EINVAL directly.
