btrfs: restore mount option info messages during mount

    After the fsconfig migration, mount option info messages are no longer
    displayed during mount operations because btrfs_emit_options() is only
    called during remount, not during initial mount.

    Fix this by calling btrfs_emit_options() in btrfs_fill_super() after
    open_ctree() succeeds. Additionally, prevent log duplication by ensuring
    btrfs_check_options() handles validation with warn-level and err-level
    messages, while btrfs_emit_options() provides info-level messages.

    Fixes: eddb1a433f26 ("btrfs: add reconfigure callback for fs_context")

btrfs: Align log messages and fix duplicates for
    NODATACOW/NODATASUM

    Fix duplicate log messages and make them the same as the log output
    messages related to NODATACOW and NODATASUM, which are output with the
    same logic.

This patch series fixes and unifies the log messages related to btrfs
mount options.

The first patch addresses a regression where mount option messages were
no longer displayed during initial mounts after the fsconfig migration.

The second patch unifies the log messages for NODATACOW and NODATASUM
options, which were being handled with the same logic but had
inconsistent and duplicate messages.

Thanks,
