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.
