module_param alttseting permissions mask (speedtch.c)

it's not very useful, but it does allow you to experiment with different
altsettings without unloading the module: write the new altsetting then
replug the modem.  It might also be useful if you want to plug in a second
modem and use a different altsetting for that.

Ciao,
