scsi: qla2xxx: Correct error handling during initialization failures
Current code misses or fails to account for proper recovery during early
initialization failures:
- Properly unwind allocations during probe() failures.
- Protect against non-initialization memory allocations during
unwinding.
- Propagate error status during HW initialization.
- Release SCSI host reference when memory allocations fail.
