irqchip/gic-v5: Clear per-CPU IRS data on teardown

In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic-v5: Clear per-CPU IRS data on teardown

IRS affinity setup publishes an IRS pointer and IAFFID state in the
per-CPU data before the remaining IRS initialization can fail. The
error path then frees the IRS data without clearing that published
state, leaving CPUs associated with freed memory.

On initialization failure and normal IRS teardown, clear the per-CPU
IRS association by removing the stale pointer to irs_data. Also
invalidate the per-CPU IAFFID state for any CPUs that were tied to the
IRS before it was freed.
