ext4: return error code when ext4_fill_flex_info() fails
After commit c89128a00838 ("ext4: handle errors on
ext4_commit_super"), 'ret' may be set to 0 before calling
ext4_fill_flex_info(), if ext4_fill_flex_info() fails ext4_mount()
doesn't return error code, it makes 'root' is null which causes crash
in legacy_get_tree().
Fixes: c89128a00838 ("ext4: handle errors on ext4_commit_super")
