Rename fb_set_reboot_flag to fastboot_set_reboot_flag so it matches all other fastboot code in the global name space. Fix the guards around them so that they're dependent on FASTBOOT, not just USB_FUNCTION_FASTBOOT. Move the weak implementation of fastboot_set_reboot_flag to fb_common.c so we can call it from non-USB fastboot code.
