Summary: alsamm channel count change bugfix

Initial Comment:
 with linux pd 0-38-4 and probably earlier versions
if eg rme9652 card is used with alsammap and the wrong
number of channels is given then pd segfaults.

for the bug see
http://sourceforge.net/tracker/index.php?func=detail&aid=1154130&group_id=55736&atid=478070


change of the sys_inchannels and
sys_out_channels and memory allocation with in stuff
exported function  

  sys_setchsr(alsamm_inchannels, alsamm_outchannels,
alsamm_sr)

after a forced change of number of channels.

GUI doesnt respect this

Additional, the two variables alsamm_inchannels and
alsamm_outchannels are initialized on open (since
multiple open can happen with use of the GUI).
