ALSA: seq: Drop the dead struct snd_seq_event_bounce

The struct describes a bounce payload of an error code followed by the
original event and its external data.  No kernel has ever sent that.
Before commit efc86691e4d8 ("ALSA: seq: Fix kernel heap address leak in
bounce_error_event()") the kernel emitted no SNDRV_SEQ_EVENT_BOUNCE at
all, and since then it sends the event record alone.

Nothing has ever read it either.  Its only accessor,
snd_seq_event_bounce_ext_data(), has had no caller for the whole git
history, and it did not even compile until commit c7e0b5bf9fff ("[ALSA]
Remove xxx_t typedefs: Sequencer") incidentally repaired the type name
it referred to, three years after the git import.  Drop the accessor
along with the struct.

This removes a definition from a UAPI header.  Since no kernel ever
produced the layout, nothing can have parsed it, but a program that
merely names the type will need to stop.
