fb: fix reconstruct statusbar illegal argument exception

Finally I got a logcat what is happening in rare cases. If the reconstruct
happens during a notification ticker was send it returns a negative
width value for the static layout and systemUI crashes.

to avoid this check before a new StaticLayout is constructed if the width is < 0 and if this
is the case abort the operation. This is in this case a legit way due that the notification
gets reconstructed during this process later so or so
