Jiri Slaby cd3a4907ee mxser: fix xmit_buf leak in activate when LSR == 0xff ...

When LSR is 0xff in ->activate() (rather unlike), we return an error.
Provided ->shutdown() is not called when ->activate() fails, nothing
actually frees the buffer in this case.

Fix this by properly freeing the buffer in a designated label. We jump
there also from the "!info->type" if now too.
