This patch fixes regression added by commit d74595278f4ab ("scsi: qla2xxx: Add multiple queue pair functionality."). When driver is not able to get reqeusted IRQs from the system, driver will attempt tp clean up memory before failing hardware probe. During this cleanup, driver assigns NULL value to the pointer which has not been allocated by driver yet. This results in a NULL pointer access.

In N2N connection the port has higher port name sends the PLOGI but not allow to send PRLI if is a target mode. Only initiator is allowed to send PRLI. Current driver code deletes old session when it receives PLOGI request. If we will not receive PLOGI request then we will not delete old session and create new session.
