ALSA: set the direction of snd_pcm_hw_params_set_*_near function to 0

[tatsuki-makino]

Describe the bug
If this is not set, the selection of open and closed intervals may not be stable.
This may have resulted in devices that could not be selected.

To Reproduce
I can't get it right :)

Expected behavior
All devices configured in ~/.asoundrc, etc. will be made available by PortAudio.

Actual behavior
Some devices configured in ~/.asoundrc are not listed by PortAudio.

Desktop (please complete the following information):

• OS: FreeBSD
• OS Version 12.4-STABLE (It has been tested. All versions are affected.)
• PortAudio version: 88ab584

Additional context
I feel I am getting better results with this patch.

This "issue" should focus on the issue :) It seems like this is a bug report and the fix is secondary. Do you think it would be appropriate to rename this ticket "FreeBSD: Some ALSA devices configured in ~/.asoundrc are not listed by PortAudio." ?

Then the possible fix is "ALSA: set the direction of snd_pcm_hw_params_set_*_near function to 0](#896 (comment))"

To Reproduce: I can't get it right :)

Please clarify. Can you reproduce it or not? What led you to believe that there is a problem?
