Above issue happens as follows:

bfad_init
error = bfad_im_module_init()
fc_release_transport(bfad_im_scsi_transport_template);
if (error)
goto ext;

ext:
bfad_im_module_exit();
fc_release_transport(bfad_im_scsi_transport_template);
--> Trigger double release

Don't call bfad_im_module_exit() if bfad_im_module_init() failed.
