[PATCH][next] ext2: remove redundant assignment to pointer end

[Colin Ian King]

Pointer is assigned a value that is never read, the assignment is
redundant and can be removed.

Cleans up clang-scan warning:
fs/ext2/xattr.c:555:3: warning: Value stored to 'end' is never read [deadcode.DeadStores]
                end = (char *)header + sb->s_blocksize;
