[PATCH 5.4 051/102] ALSA: seq: oss: Fix running status after receiving sysex

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@xxxxxxx>

commit 6c3171ef76a0bad892050f6959a7eac02fb16df7 upstream.

This is a similar bug like the previous case for virmidi: the invalid
running status is kept after receiving a sysex message.

Again the fix is to clear the running status after handling the sysex.
