ivshmem-test: Improve test cases /ivshmem/server-*
Document missing test: behavior with MSI-X present but not enabled.
For MSI-X, we test and clear the interrupt pending bit before testing
the interrupt. For INTx, we only clear. Change to test and clear for
consistency.
Test MSI-X vector 1 in addition to vector 0.
Improve comments.
