tests: Fix broken ivshmem-server-msi/-irq tests 

Broken with commit b4ba67d9a7 ("libqos: Change PCI accessors to take
opaque BAR handle") a while ago, but nobody noticed since the tests are
not run by default: The msix_pba_bar is not correctly initialized
anymore if bir_pba has the same value as bir_table. With this fix,
"make check SPEED=slow" should work fine again.
