[ion] 23146: [AUDIT] - State.c is clean, it is merely a collection of trivial ~10 line wrappers around the actual kernel (Ke) functions which do the work. - Rename suspend.c to state.c (since it also had resume APIs) and add alert APIs from kthread to it too. - Fix a bug in one of the alert APIs which was probing for a valid pointer even if the caller had given NULL (which is valid if the caller doesn't want the previous state returned).

Log:
[AUDIT] - State.c is clean, it is merely a collection of trivial ~10 line wrappers around
the actual kernel (Ke) functions which do the work.
- Rename suspend.c to state.c (since it also had resume APIs) and add alert APIs from
kthread to it too.
- Fix a bug in one of the alert APIs which was probing for a valid pointer even if the
caller had given NULL (which is valid if the caller doesn't want the previous state
returned).
