During nvme target initialization discovery subsystem is initialized
before "nvmet" debugfs directory is created. This results in discovery
subsystem debugfs directory to be created in debugfs root directory.

nvmet_init() ->
nvmet_init_discovery() ->
nvmet_subsys_alloc() ->
nvmet_debugfs_subsys_setup()

In other words, the codepath above is exeucted before nvmet_debugfs is
created. We get /sys/kernel/debug/nqn.2014-08.org.nvmexpress.discovery
instead of /sys/kernel/debug/nvmet/nqn.2014-08.org.nvmexpress.discovery.
Move nvmet_init_discovery() call after nvmet_init_debugfs() to fix it.
