Chad Dupuis 36008cf118 [SCSI] qla2xxx: Fix request queue null dereference. 
If an invalid IOCB is returned on the response queue then the index into the
request queue map could be invalid and could return to us a bogus value. This
could cause us to try to deference an invalid pointer and cause an exception.

If we encounter this condition, simply return as no context can be established
for this response.

* This function is for formatting and logging log messages.
* It is to be used when vha is not available and pci is available,
* i.e., before host allocation. It formats the message and logs
* it to the messages file. All the messages are logged irrespective
* of the value of ql2xextended_error_logging.
* parameters:
* level: The level of the log messages to be printed in the
* messages file.
* pdev: Pointer to the struct pci_dev.
* id: This is a unique id for the level. It identifies the
* part of the code from where the message originated.
* msg: The message to be displayed.
