8250: ratelimit LSR safety check engaged warning.
On my BIOSTAR TA890FXE the ttyS0 ends up spewing:
[904682.485933] ttyS0: LSR safety check engaged!
[904692.505895] ttyS0: LSR safety check engaged!
[904702.525972] ttyS0: LSR safety check engaged!
[904712.545967] ttyS0: LSR safety check engaged!
[904722.566125] ttyS0: LSR safety check engaged!
..
lets limit it so it won't be the only thing visible
in the ring buffer.
