Summary: alsamm channels should not default to min.available channels

Initial Comment:
with alsamm the requested number of channels is ignored.
instead it defaults to "0" which is then clamped
between the minimum and maximum number of channels the
hw supports.
while most cards might only support a fixed number of
channels (minch==maxch), there are other cards (or
rather: drivers) that allow to really select the number
of mmapped channels: e.g. the RME MADI can use any of
1..64 channels in this mode.
with pd's defaults you only get "1" channel (but you
pay for 64!)

attached is a little patch that rather uses the maximum
available channels as a "default" fallback. (patch
against 0.39-2, but very small so might apply to other
versions as well)

of course, the cleanest solution would be to accept the
#channels requested by the user.
