The "nofua" attribute is used in the File-Storage Gadget but the
functions handling it are defined in storage_common.c (which may be
not a bad thing if anyone will want to port tho "nofua" attribute to
mass storage function) which causes the following warnings:
drivers/usb/gadget/storage_common.c:718: \
warning: ‘fsg_show_nofua’ defined but not used
drivers/usb/gadget/storage_common.c:782: \
warning: ‘fsg_store_nofua’ defined but not used
Adding __maybe_unused fixes this issue.
