target/xtensa: Correct assert condition in handle_interrupt()
In commit ad18376b90c8101 we added an assert that the level value was
in-bounds for the array we're about to index into. However, the
assert condition is wrong -- env->config->interrupt_vector is an
array of uint32_t, so we should bounds check the index against
ARRAY_SIZE(...), not against sizeof().
Resolves: Coverity CID 1507131
Fixes: ad18376b90c8101 ("target/xtensa: Assert that interrupt level is within bounds")
