alsa-mixer: When setting hw volume, always round up with playback and down with capture.

The previous logic in ade0a6f88464d8aecf83982d400ccfc402341920
does not work with for input volumes.

This was discussed on the mailing list:

https://tango.0pointer.de/pipermail/pulseaudio-discuss/2011-May/010091.html

This approach can introduce a problem when setting the volumes
for sources. What follows is Tanu Kaskinen's analysis:

[quote]
I'll quote the log:

D: protocol-native.c: Client pavucontrol changes volume of source alsa_input.pci-0000_00_1b.0.analog-stereo.
D: alsa-source.c: Requested volume: 0:  45% 1:  45%
D: alsa-source.c:            in dB: 0: -20.71 dB 1: -20.71 dB

D: alsa-source.c: Calculated software volume: 0: 101% 1: 101% (accurate-enough=no)
D: alsa-source.c:                      in dB: 0: 0.29 dB 1: 0.29 dB
D: source.c: Volume going up to 29273 at 270475970821
D: source.c: Volume change to 29273 at 270475970821 was written 34 usec late
D: alsa-source.c: Written HW volume did not match with the request: 0: 45% 1:  45% (request) != 0:  42% 1:  42%
D: alsa-source.c:                                            in dB: 0: -21.00 dB 1: -21.00 dB (request) != 0: -22.50 dB 1: -22.50 dB

Looking at the last line, the requested volume seems to hit exactly the
right step (-21.00dB), but for some reason Alsa decides to choose
something else. I'm pretty sure that this happens because of rounding
errors. In the first phase we ask Alsa what dB value we should set, and
it returns -21.00 dB. The value is given as a long int, but we convert
that to pa_cvolume. Then when we set the volume, we convert the
pa_cvolume value back to a long integer. At this point I believe it gets
converted to -2101. This is not visible in the debug message for some
reason - the rounding algorithm must be different from what was used
with the pa_cvolume -> long conversion.

Another reason to keep this integrated with the AEC module is that the
