This patch is based on a problem and solution from Maurizio Lombardi
where bnx2fc isn't consistent in which device struct we using for DMA
map and unmap operations. Make them consistent by using dma_sg_unmap
in bnx2fc_unmap_sg_list like bnx2fc_map_sg.

The PCI register read checking introduced in commit fe1b806f4f71
("qla2xxx: Disable adapter when we encounter a PCI disconnect") is
active during driver probe. Hold off scheduling any board removal until
the driver probe has completed. This ensures that the the board_disable
work structure is initialized and more importantly, avoids racing
qla2x00_probe_one.

Introduce mutual exclusion between the qla2xxx_remove_one PCI driver
callback and qla2x00_disable_board_on_pci_error, which is scheduled as
board_disable work by qla2x00_check_reg{32,16}_for_disconnect:
* Leave the driver-specific data attached to the underlying PCI device
intact in qla2x00_disable_board_on_pci_error, so that qla2x00_remove_one
has enough breadcrumbs to determine that any board_disable work has been
completed.
* In qla2xxx_remove_one, set a bit to prevent any subsequent
board_disable work from scheduling, then cancel and wait until pending
work has completed.
* Reuse the PCI device enable count check in qla2x00_remove_one to
determine if board_disable has occured. The original purpose of this
check was unnecessary since the driver remove function wasn't called
when the probe fails.

When a second(kdump) kernel starts and the hard reset method is used
the driver calls pci_disable_device without previously enabling it,
so the kernel shows a warning -
[ 16.876248] WARNING: at drivers/pci/pci.c:1431 pci_disable_device+0x84/0x90()
[ 16.882686] Device hpsa
disabling already-disabled device
...
This patch fixes it, in addition to this I tried to balance also some other pairs
of enable/disable device in the driver.
Unfortunately I wasn't able to verify the functionality for the case of a sw reset,
because of a lack of proper hw.
