[PATCH] ext4: remove redundant assignment to node

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Pointer 'node' is assigned a value that is never read, node is
later overwritten when it re-assigned a different value inside
the while-loop.  The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
