irqchip/gic-v3-its: Don't free a vPE table shared with another ITS
On GICv4.1, its_alloc_tables() copies a sibling's vPE table baser
rather than allocating one, but its_free_tables() frees it like the
rest. A probe failure on the copying ITS then frees pages the enabled
sibling still points GITS_BASER2 at, and the kernel comes up running
on that sibling.
Mark a shared table so its_free_tables() skips it.
