[PATCH] ext4: remove redundant assignment to variable split_flag1

[Colin Ian King]

Variable split_flag1 is being assigned a value that is never read,
it is being re-assigned a new value in the following code block.
The assignment is redundant and can be removed.

Cleans up clang scan build warning:
fs/ext4/extents.c:3371:2: warning: Value stored to 'split_flag1' is
never read [deadcode.DeadStores]
