ALSA: oxfw: use workqueue instead of tasklet for scs1x
This commit replaces tasklet with workqueue for scs1x functionality of
ALSA oxfw driver.
This driver transfers MIDI message specific for SCS.1m and SCS.1d. This
task is currently done in software IRQ context of tasklet. In a view of
system, this context is limited resources and some important drivers (at
least, more important than ALSA oxfw driver) use the context as its
bottom-harf.
If the work to transfer MIDI messages is done within a time, it's better
to use the other context for the work. Actually, with recent CPUs, the
work will be scheduled within a time. This is a reason of this commit.
