fix for #159 #158

[neelgala]

This change will fix the issues pointed out in #159 and #158. The test no longer assumes the reset "type" of mcontrol to be 2 and thus explicitly defines it while updating tdata1.

Also tdata1 is read-back to see if the particular mcontrol fields are valid for the implementation else skip the test-part.

Thanks, merged (but with the commented-out code deleted)
