RDMA/iwpm: Fix uninitialized error code in iwpm_send_mapinfo()

Browse source

[ Upstream commit 302d6424e4 ]

With gcc-4.1.2:

    drivers/infiniband/core/iwpm_util.c: In function ‘iwpm_send_mapinfo’:
    drivers/infiniband/core/iwpm_util.c:647: warning: ‘ret’ may be used uninitialized in this function

Indeed, if nl_client is not found in any of the scanned has buckets, ret
will be used uninitialized.

Preinitialize ret to -EINVAL to fix this.
