Chunwei Chen e68e938f54 Fix zfs_get_data access to files with wrong generation If TX_WRITE is create on a file, and the file is later deleted and a new directory is created on the same object id, it is possible that when zil_commit happens, zfs_get_data will be called on the new directory. This may result in panic as it tries to do range lock. This patch fixes this issue by record the generation number during zfs_log_write, so zfs_get_data can check if the object is valid.
