The CUST_SCRATCHPAD_CSR register is used for marking if FW cleanup is
needed. This is used in a crash kernel scenario. Do no use this register as
it is not available for some functions. Instead, always issue an FLR when
a function is probed *except* when VFs are preset (enabled in the previous
PF load).

Setting the PCI MRRS to a value of 4096 (overriding the system decided
value) had provided perf improvement in TX.
But, IBM has provided feedback that on POWER platforms, this value is set
by the system firmware, and drivers modifying this value can cause
unpredictable results (like EEH errors.) So, backing off this change.
On POWER7 platforms most slots, it seems, do get a MRRS of 4096.

This patch reverts the following commit:
"be2net: Modified PCI MaxReadReq size to 4096 bytes"
commit 5a56eb10.

Calling pci_disable_sriov() while VFs are assigned to VMs causes
kernel panic. This patch uses PCI_DEV_FLAGS_ASSIGNED bit state of the
VF's pci_dev to avoid this. Also, the unconditional function reset cmd
issued on a PF probe can delete the VF configuration for the
previously enabled VFs. A scratchpad register is now used to issue a
function reset only when needed (i.e., in a crash dump scenario.)
