[ecasound] Memory issue on exit in 2.9.1

Hi Kai,

I got this output from a Nama user. Thought it may be
helpful to you.

He ran three *-register commands, then exited, leading to
this message:

*** Error in `ecasound': double free or corruption (!prev): 0x000000dcc9ed0590 ***

The full log follows.

Thank you for your attention.

Joel
