usb: gadget: f_fs: Limit the maximum length of data transferring

When the ffs daemons request transfer with large size buffer, the usb
subsystems below cannot filled the buffer at once and then the request
is stalled in f_fs_epfile_io function. In order to prevent this
situation, this limits maximum length of data as PAGE_SIZE.
