Just passing pointers rids us of these warnings and improves readability.

[SCSI] zfcp: Add trace records for recovery thread and its queues
We are not supposed to poke inside semaphore.

Saving on line breaks, improving readability, by shortening excessive
function names and identifiers, by simplifying some functions call
chains, and by simplifying nesting of some data structure.

Change zfcp_dbf_timestamp() so that it just calculates timespec from
timestamp. First step to be able to rip this code out of zfcp.
Besides, this change makes it easier to rip out old-style debug view
functions.

This patch writes trace records for various phases of a recovery action:
action being created, action being processed, action continueing
asynchronously, action gone, action timed out, action dismissed etc.

This patch writes a trace record which provides information about state
changes for adapters, ports and units, e.g. target failure, targets becoming
online, targets being temporarily blocked due to pending recovery, targets
which have been recovered successfully etc.

This patch writes trace records which provide information about the
operation of the zfcp error recovery thread and the queues it works
on.

This patch adds per request hardware debugging data to the trace
record which is written per request. It's a replacement for some sad
kernel message based debugging code. Considering the amount of trace
data, printk() is not suitable for this stuff. Writing binary traces
is more efficient. In addition we got all information in one place.
The QTCB trace data is only dumped for requests other than SCSI
requests. Otherwise we would flood the trace ring buffer. We are
mostly interested in non-SCSI, recovery related requests here anyway.
This patch also works around a known hardware bug. It truncates QTCB
traces so that we do not save unused areas of the hardware trace.
