Btrfs: skip search tree for REG files
It is really unnecessary to search tree again for @gen, @mode and @rdev in the case of REG inodes' creation, as we've got btrfs_inode_item in sctx, and @gen, @mode and @rdev can easily be fetched. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: Josef Bacik <jbacik@fb.com>
