sg_remove_sfp_usercontext() must not use sg_device_destroy() after
calling scsi_device_put().

sg_device_destroy() is accessing the parent scsi device request_queue.
Which will already be set to NULL when the preceding call to
scsi_device_put() removed the last reference to the parent scsi device.

The resulting NULL pointer exception will then crash the kernel.
