floppy: don't use PREPARE_[DELAYED_]WORK
PREPARE_[DELAYED_]WORK() are being phased out. They have few users
and a nasty surprise in terms of reentrancy guarantee as workqueue
considers work items to be different if they don't have the same work
function.
floppy has been multiplexing floppy_work and fd_timer with multiple
work functions. Introduce floppy_work_workfn() and fd_timer_workfn()
which invoke floppy_work_fn and fd_timer_fn respectively and always
use the two functions as the work functions and update the users to
set floppy_work_fn and fd_timer_fn instead of overriding work
functions using PREPARE_[DELAYED_]WORK().
It would probably be best to route this with other related updates
through the workqueue tree.
Lightly tested using qemu.
