[PATCH] Btrfs-progs: convert: do not clear header rev

[Liu Bo <bo.li.liu@oracle.com>]

So btrfs_set_header_flags() vs btrfs_set_header_flag, the difference is sort of
similar to "=" vs "|=", when creating and initialising a new extent buffer,
convert uses the former one which clears header_rev by accident.
