btrfs: allocate path earlier at btrfs_log_new_name()

Instead of allocating the path after joining the log transaction, allocate
it before so that we're not delaying log commits for the rare cases where
the allocation takes a significant time (under memory pressure and all
slabs are full, there's the need to allocate a new page, etc).
