sysfs: add struct file* to bin_attr callbacks
Added an extra struct file * parameter at the beginning, which the
arcmsr binary attribute additions didn't have. Fix this to prevent
nasty crashes.

This patch removes malloc(), free(), and printf() wrappers from the aic7xxx
SCSI driver. I didn't use pr_debug for printf because of some 'clever' uses of
printf don't compile with the pr_debug. I didn't fix the overeager uses of
GFP_ATOMIC either because I wanted to keep this patch as simple as possible.

Once the device goes *missing*, driver blocks the session
ie iscsi_block_session() to stall the I/O. So after device
comes back *online*, driver needs to unblock the session ie
iscsi_unblock_session(), else I/Os will fail even if
ddb_state is ONLINE.

- Add debugfs support to obtain firmware trace, driver trace
and read/write to registers.
- debugfs hierarchy:
/sys/kernel/debug/bfa/host#
where the host number corresponds to the one under /sys/class/scsi_host/host#
- Following are the new debugfs entries added:
drvtrc: collect current driver trace
fwtrc: collect current firmware trace.
fwsave: collect last saved fw trace as a result of firmware crash.
regwr: write one word to chip register
regrd: read one or more words from chip register.

This patch fixes 3 bugs in vport create/delete.
1) Replace scsi_add_host() with scsi_add_host_with_dma()
2) Fix rmmod hang when there are vports configured. This is due to a race
condition between the workqueue destroy in pci remove context and the vport
delete works being handled. The fix is to use a counter to track the
vport delete work, so that workqueue destroy will not be called until all
configured vports are deleted from workqueue.
3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed
to be deleted dynamically. However, if someone try to delete it, it leaves the
vport is wrong state. The fix is to restore the vport back to original state
when the attempt to delete pbc vport delete is failed.
