Above issue happens as follows:

bfadinit error = bfadimmoduleinit() fcreleasetransport(bfadimscsitransporttemplate); if (error) goto ext;

ext: bfadimmoduleexit(); fcreleasetransport(bfadimscsitransport_template); --> Trigger double release

Don't call bfadimmoduleexit() if bfadimmoduleinit() failed.
