ALSA: seq: Fix missing NULL check at remove_events ioctl
commit 030e2c78d3a91dd0d27fef37e91950dde333eba1 upstream.
snd_seq_ioctl_remove_events() calls snd_seq_fifo_clear()
unconditionally even if there is no FIFO assigned, and this leads to
an Oops due to NULL dereference. The fix is just to add a proper NULL
check.
