sched: Fix kABI for task->pasid_activated

CVE: NA

Intel-SIG: sched: Fix kABI for task->pasid_activated.

-------------------------------------------------

In commit
("sched: Define and initialize a flag to identify valid PASID in the task"),
a new single bit field 'pasid_activated' is added to the middle of
'struct task_struct' that causes kABI breakage.

Fix it by using KABI_FILL_HOLE() API for task->pasid_activated.
