ext4: remove redundant o_start statement
The if will goto out of the loop, and until the end of the function execution, o_start will not be used again. The clang_analyzer complains as follows: fs/ext4/move_extent.c:635:5 warning: Value stored to 'o_start' is never read Reported-by: Zeal Robot <zealci@zte.com.cn> Signed-off-by: luo penghao <luo.penghao@zte.com.cn> Link: https://lore.kernel.org/r/20211208075157.404535-1-luo.penghao@zte.com.cn Signed-off-by: Theodore Ts'o <tytso@mit.edu>
