"scsi: aacraid: Fix double-free on probe failure. aac_probe_one() calls
hardware-specific init functions through the aac_driver_ident::init
pointer, all of which eventually call down to aac_init_adapter(). If
aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member. After the
hardware-specific init function returns an error, aac_probe_one() goes
down an error path that frees the memory pointed to by
aac_dev::queues, resulting in a double-free.

This plugin only works with Tenable.ot.
