scsi: ufs: exynos: Correct sync pattern mask timing comment

Fix the comment for SYNC_LEN_G2 in exynos_ufs_config_sync_pattern_mask().
The actual value is 40us, not 44us, matching the configured mask timing.
This change improves code clarity and avoids potential confusion for
readers and maintainers.

No functional changes.
