[ Upstream commit 0777a3fb98f0ea546561d04db4fd325248c39961 ]

Correct driver's ISR accessing a data structure member that has not been
fully initialized during driver initialization.

The pqi queue groups can have uninitialized members when an interrupt
fires. This has not resulted in any driver crashes. This was found during
our own internal testing. No bugs were ever filed.
