[SCSI] mptfusion: Proper error handling is added after mpt_config timeout
Added proper error handling after mpt_config. Now check of MPI_IOCSTATUS_CONFIG_INVALID_PAGE is added. If error is MPI_IOCSTATUS_CONFIG_INVALID_PAGE, driver will return -ENODEV. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
