btrfs: avoid path allocations when dropping extents during log replay 



We can avoid a path allocation in the btrfs_drop_extents() calls we have
at replay_one_extent() and replay_one_buffer() by passing the path we
already have in those contextes as it's unused by the time they call
btrfs_drop_extents().
