floppy: fix function pointer cast warnings

Browse source

clang-16 complains about a control flow integrity (kcfi) violation
casting between incompatible pointers:

drivers/block/floppy.c:2001:11: error: cast from 'void (*)(void)' to 'done_f' (aka 'void (*)(int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
 2001 |         .done           = (done_f)empty
      |                           ^~~~~~~~~~~~~

Just add another empty function with the correct prototype as a
workaround.

The warning is for code that was added before the start of the normal
git history, but I tracked it done to an early change in the reconstructed
linux-history.git.
