usb: gadget: f_mass_storage: ignore class requests while inactive
SET_CONFIGURATION is handled asynchronously by the mass-storage thread.
A class request can arrive after the composite core selects the function
but before the thread installs common->fsg, or while the function is being
disabled.
fsg_setup() already rejects this state with -EOPNOTSUPP, but checking it
through fsg_is_set() also emits a warning. Check the active function
directly so normal requests during a configuration transition are rejected
without hiding fsg_is_set() warnings from other internal paths.
