Fix SDF_DIRTY handling, eliminate useless SDF_FLUSHING. The sd_flush()
called from the last sdclose() on a device will now reset SDF_DIRTY
after submitting the SYNCHRONIZE CACHE command. sddone() need not
worry about SDF_DIRTY since it was never called for the SYNCHRONIZE
CACHE command anyway.
This eliminates a spurious SYNCHRONIZE CACHE command being issued for
every sd device from sd_shutdown().
