In presence of multiple functions, current driver implementation does not
guarantee that the FW dump is taken by the same function that forces it.
Change it by adding a fw reset owner flag that could be changed in the device
reset path and only when a function determines that it needs to reset it.

Machines are getting deadlock in four node cluster environment.
All nodes are accessing (find /gfs2 -depth -print|cpio -ocv > /dev/null)
200 GB storage on a GFS2 filesystem.
This result in memory fragmentation and driver receives 18 frags for
1448 byte packets.
For non tso packet, fw drops the tx request, if it has >14 frags.

Fixing it by pulling extra frags.

Driver is reading flash fw version from defined address, this address
may be invalid. Indeed Driver should read address for fw version through
flash layout table. Flash layout table has defined region and address for
fw version address should be read from fw image region.

Driver has check for old firmware, this bug can cause driver load fail.
This patch will try to read fw version from flash image region, if that fails,
read from defined address.

In kdump environment do not depend upon reset_devices parameter
to reset the pci function as this parameter may become obsolete.
Instead use an adapter specific mechanism to determine if the pci
function needs to be reset.

Per function refcount is maintained in driver, which is set in probe
and reset in remove handler of adapter. If the probe detects the count
as non zero then reset the function.
