From: chongjiapeng <jiapeng.chong@linux.alibaba.com>
slot and leaf are being initialized to path->slots[0] and path->nodes[0], but this is never read as slot and leaf is overwritten later on. Remove the redundant assignment.
Cleans up the following clang-analyzer warning:
fs/btrfs/tree-log.c:6125:7: warning: Value stored to 'slot' during its initialization is never read [clang-analyzer-deadcode.DeadStores].
