Jaroslav Kysela 6d7a47e849 ALSA: hda/hdmi: Fix the converter reuse for the silent stream
[ Upstream commit 5f80d6bd2b01de4cafac3302f58456bf860322fc ]

When the user space pcm stream uses the silent stream converter,
it is no longer allocated for the silent stream. Clear the appropriate
flag in the hdmi_pcm_open() function. The silent stream setup may
be applied in hdmi_pcm_close() (and the error path - open fcn) again.

If the flag is not cleared, the reuse conditions for the silent
stream converter in hdmi_choose_cvt() may improperly share
this converter.
