[ofa-general] [PATCH] RDMA/nes: Guard tmp_addr definition with CONFIG_INFINIBAND_NES_DEBUG

If CONFIG_INFINIBAND_NES_DEBUG is not defined, nes_debug is defined
away. Since the invocation of nes_debug in find_listener is the only
use of tmp_addr, GCC complains that the latter is never used:
drivers/infiniband/hw/nes/nes_cm.c: In function ‘find_listener’:
drivers/infiniband/hw/nes/nes_cm.c:857: warning: unused variable ‘tmp_addr’
To avoid this, only define tmp_addr if it will be used. That is, if
CONFIG_INFINIBAND_NES_DEBUG is defined.
