[PULL 08/12] ossaudio: disable poll mode can't be reached

[Gerd Hoffmann]

From: Volker Rümelin <address@hidden>

Currently there is no way to disable poll mode in
oss_enable_out and oss_enable_in when it was enabled before.
The enable code path always resets the poll mode state variable.

Fixes: b027a538c6 "oss: Remove unused error handling of qemu_set_fd_handler"
