Subject: [PATCH v4 2/2] ocfs2: Convert remaining read-only checks to ocfs2_emergency_state
Now that the centralized `ocfs2_emergency_state()` helper is available,
refactor remaining filesystem-wide checks for `ocfs2_is_soft_readonly`
and `ocfs2_is_hard_readonly` to use this new function.
To ensure strict consistency with the previous behavior and guarantee
no functional changes, the call sites continue to explicitly return
-EROFS when the emergency state is detected. This standardizes the
check logic while preserving the existing error handling flow.
