Add a 'hba_serial' property to the megasas driver. Originally
it would be using a pointer value which would break migration.

This patch introduces a new property 'sas_address' which
allows the user to specify the SAS address for the HBA.
The default address is following the NAA locally assigned
identifier format with the locally assigned address
0x525400 as used eg for the MAC addresses.
The lower bytes are set to the pci address which
will ensure uniqueness for the local machine.
The port addresses are now calculated based on the magic
number 0x1221 (which is found in real hardware, too) plus
the device number.

Commit f90c2bcdbc changed
PCIUnregisterFunc, therefore the function prototype
needs an update.
megasas.o is currently not linked, so this bug was not
detected by the buildbots.

scsi_req_abort is for terminating a command with a non-zero status.
The ABORT task management function is invoked by scsi_req_cancel.
In fact, ABORTED_COMMAND is a sense key, not a SAM status code.

trace_megasas_dcmd_dump_frame() takes 9 arguments, which is
rather much. Plus the trace infrastructure doesn't support
it. As we can get the information via other means it's pointless
to have it in the driver, so rather use some proper trace
point here and remove the old one.

This patch adds an emulation for the LSI Megaraid SAS 8708EM2 HBA.
I've tested it to work with Linux, Windows Vista, and Windows7.
