After commit 9d2e9d66 mptsas driver fails to allocate
memory for the MPT chain buffers for second 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.
This patch is an attempt to fix it.
