usb: f_mass_storage: limit number of reported LUNs

Browse source

commit 8515bac01a upstream.

Mass storage function created via configfs always reports eight LUNs
to the hosts even if only one LUN has been configured.  Adjust the
number when the USB function is allocated based on LUNs that user
has created.
