mptsas: Fix issue with chain pools allocation on katmai
commit f1053a7ca9ce095d95bcc1cf41684c5e4f3e7751 upstream.
Since commit 9d2e9d66a3f032667934144cd61c396ba49f090d
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.
