genirq/test: Drop CONFIG_GENERIC_IRQ_MIGRATION assumptions

Not all platforms use the generic IRQ migration code, even if they select
GENERIC_IRQ_MIGRATION. (See, for example, powerpc / pseries_cpu_disable().)

If such platforms don't perform managed shutdown the same way, the interrupt
may not actually shut down, and these tests fail:

[    4.378073][    T1] # irq_test_cases: pass:3 fail:1 skip:0 total:4

Rather than test that PowerPC performs migration the same way as the
unterrupt core, just drop the state checks. The point of the test was to
ensure that the code kept |depth| balanced, which still can be tested for.
