Commit 03080e5cbe0222744173d3e726f6ba5d13b7f04e is causing some warning
during compilation.

tmp_addr is an unused variable if CONFIG_INFINIBAND_NES_DEBUG is
 not used. Causing the following Warning.

drivers/infiniband/hw/nes/nes_cm.c: In function ‘find_node’:
drivers/infiniband/hw/nes/nes_cm.c:781: warning: unused variable ‘tmp_addr’
drivers/infiniband/hw/nes/nes_cm.c: In function ‘find_listener’:
drivers/infiniband/hw/nes/nes_cm.c:820: warning: unused variable ‘tmp_addr’
