Subject[PATCH] infiniband: shut up a maybe-uninitialized warning
The powerpc64 default configuration leads to warnings for the infiniband
core code:

infiniband/core/cma.c: In function 'cma_get_net_dev':
infiniband/core/cma.c:1242:12: warning: 'src_addr_storage.sin_addr.s_addr' may be used uninitialized in this function [-Wmaybe-uninitialized]

The code looks correct to me, and I don't see the warnings on the
other architectures, so this is a dumb change to add an unneeded
initialization to the variables in order to shut up the warning.
