scsi: fix regression and honor bootindex again for legacy drives

Browse Source 
Commit 3089637461 ("scsi: Don't ignore most usb-storage properties")
removed the call to object_property_set_int() and thus the 'set'
method for the bootindex property was also not called anymore. Here
that method is device_set_bootindex() (as configured by
scsi_dev_instance_init() -> device_add_bootindex_property()) which as
a side effect registers the device via add_boot_device_path().

As reported by a downstream user [0], the bootindex property did not
have the desired effect anymore for legacy drives. Fix the regression
by explicitly calling the add_boot_device_path() function after
checking that the bootindex is not yet used (to avoid
add_boot_device_path() calling exit()).
