Bugfix #4223

Browse Source 
Sequencer:
A call to view2d_do_locks() got accidentally added in main drawing loop,
causing an infinite loop of redraws when this option was used with more
sequence windows open.

Added missing view2d_do_locks() to zooming in Sequence window. Also
cleaned this call a bit.
