Steffen Maier 33b0e54db4 scsi: zfcp: trace channel log even for FCP command responses 
[ Upstream commit 100843f176 ]

While v2.6.26 commit b75db73159 ("[SCSI] zfcp: Add qtcb dump to hba debug
trace") is right that we don't want to flood the (payload) trace ring
buffer, we don't trace successful FCP command responses by default.  So we
can include the channel log for problem determination with failed responses
of any FSF request type.

Fixes: b75db73159 ("[SCSI] zfcp: Add qtcb dump to hba debug trace")
Fixes: a54ca0f62f ("[SCSI] zfcp: Redesign of the debug tracing for HBA records.")
