btrfs: remove redundant initialization of variables in log_new_ancestors

Browse Source 
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 warnings:

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]

It's been there since b8aa330d2acb ("Btrfs: improve performance on fsync
of files with multiple hardlinks") without any usage so it's safe to be
removed.
