austinchang 8679d2687c btrfs: initialize inode::file_extent_tree after i_mode has been set ...

btrfs_init_file_extent_tree() uses S_ISREG() to determine if the file is
a regular file. In the beginning of btrfs_read_locked_inode(), the i_mode
hasn't been read from inode item, then file_extent_tree won't be used at
all in volumes without NO_HOLES.

Fix this by calling btrfs_init_file_extent_tree() after i_mode is
initialized in btrfs_read_locked_inode().

Fixes: 3d7db6e8bd ("btrfs: don't allocate file extent tree for non regular files")
