Subject: [PATCH] usb: gadget: f_mass_storage: change default value of the removable parameter

This commit changes the default value of the removable module parameter
from “y” to “n”.  This comes with line with file_storag's default and
seems to be a better default.

Alternatively I can add a warning about the default being changed and
schedule the change for the future.  Dunno if it's worth it.
