OvmfPkg: PciHostBridgeDxe: release resources on driver entry failure
The entry point of the driver, InitializePciHostBridge(), leaks resources
(and installed protocols) in the following cases:
- The first root bridge protocol installation fails. In this case, the
host bridge protocol is left installed, but the driver exits with an
error.
- The second or a later root bridge protocol installation fails. In this
case, the host bridge protocol, and all prior root bridge protocols, are
left installed, even though the driver exits with an error.
Handle errors correctly: roll back / release / uninstall resources when
aborting the driver.
