[PATCH 4.2.y-ckt 191/206] IB/srp: Print "ib_srp: " prefix once

[Kamal Mostafa]

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Bart Van Assche <bart.vanassche@xxxxxxxxxxx>

commit cf1acab7d75652a372ee5b9c996689d518914e83 upstream.

pr_debug() already prints prefix PFX. Avoid that PFX is printed
twice if the debug statement in srp_add_target() is enabled.

Fixes: 34aa654ecb8e ("IB/srp: Avoid that I/O hangs due to a cable pull during LUN scanning")
