Subject: [PATCH][next] btrfs: remove redundant initialization of variables leaf and slot

The variables leaf and slot are initialized when declared but the values
assigned to them are never read as they are being re-assigned later on.
The initializations are redundant and can be removed. Cleans up clang
scan build warings:

fs/btrfs/tree-log.c:6797:25: warning: Value stored to 'leaf' during its
initialization is never read [deadcode.DeadStores]
fs/btrfs/tree-log.c:6798:7: warning: Value stored to 'slot' during its
initialization is never read [deadcode.DeadStores]
