irqchip/gic-v3-its: Avoid parsing _indirect_ twice for Device table

Browse Source 
commit 8d565748b6035eeda18895c213396a4c9fac6a4c upstream.

In current logic, its_parse_indirect_baser() will be invoked twice
when allocating Device tables. Add a *break* to omit the unnecessary
and annoying (might be ...) invoking.
