Subject: [PATCH -next] infiniband: siw: remove set but not used variables 'rv'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/infiniband/sw/siw/siw_cm.c: In function siw_cep_set_inuse:
drivers/infiniband/sw/siw/siw_cm.c:223:6: warning: variable rv set but not used [-Wunused-but-set-variable]

It is not used since commit 6c52fdc244b5("rdma/siw: connection management")
