[SCSI] mptsas: Fix issue with chain pools allocation on katmai
Since commit 9d2e9d66 mptsas driver fails to allocate memory for the MPT chain buffers for second LSI adapter on PPC440SPe Katmai platform: ... ioc1: LSISAS1068E B3: Capabilities={Initiator} mptbase: ioc1: ERROR - Unable to allocate Reply, Request, Chain Buffers! mptbase: ioc1: ERROR - didn't initialize properly! (-3) mptsas: probe of 0002:31:00.0 failed with error -3 This commit increased MPT_FC_CAN_QUEUE value but initChainBuffers() doesn't differentiate between SAS and FC causing increased allocation for SAS case, too. Later pci_alloc_consistent() fails to allocate increased chain buffer pool size for SAS case. Provide a fix by looking at the bus type and using appropriate MPT_SAS_CAN_QUEUE value while calculation of the number of chain buffers.
