libext2fs: ind_punch() must not stop examining blocks prematurely
When we're iterating the main loop in ind_punch(), "offset" tracks how
far we've progressed into the block map, "start" tells us where to
start punching, and "count" tells us how many blocks we are to punch
after "start". Therefore, we would like to break out of the loop once
the "offset" that we're looking at has progressed past the end of the
punch range. Unfortunately, if start !=0, the if-break clause in the
loop causes us to break out of the loop early.
Therefore, change the breakout test to terminate the loop at the
correct time.
