timers/migration: Update stale @online doc to @available

Commit 8312cab5ff ("timers/migration: Rename 'online' bit to
'available'") renamed the 'online' field of struct tmigr_cpu to
'available'. The kernel doc comment above the struct still describes the
old field name.

Update it to reflect the actual field name and use the 'available' wording
in the description.
