[SCSI] mpt fusion: fix for mounted raid volume filesytem that goes read-only
If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

Currently accessing the scsi host private data is rather messy because
it comes as an unsigned long that always needs a cast first. This patch
introduces a helper that does the cast called shost_priv. It's similar
in spirit to netdev_priv for network drivers.
This is the first patch introducing the macro, and the second patch
in the series will convert esp and it's subdrivers as an example.
Further conversion will wait until the helper is in the tree to make
patch juggling easier.

NFS: Fix a refcount leakage in O_DIRECT
The current code is leaking a reference to dreq->kref when the calls to
nfs_direct_read_schedule() and nfs_direct_write_schedule() return an
error.
This patch moves the call to kref_put() from nfs_direct_wait() back into
nfs_direct_read() and nfs_direct_write() (which are the functions that
actually took the reference in the first place) fixing the leak.
Thanks to Denis V. Lunev for spotting the bug and proposing the original
fix.
