[PATCH] timers/migration: Update stale @online doc to @available

[Zhan Xusheng]

Commit 8312cab5ff47 ("timers/migration: Rename 'online' bit to
'available'") renamed the 'online' field of struct tmigr_cpu to
'available'. The kdoc comment above the struct still describes the
old field name.

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

Fixes: 8312cab5ff47 ("timers/migration: Rename 'online' bit to 'available'")
