net/smc: add missing error check in smc_clc_prfx_set()
Coverity stumbled over a missing error check in smc_clc_prfx_set():
*** CID
1475954: Error handling issues (CHECKED_RETURN)
/net/smc/smc_clc.c: 233 in smc_clc_prfx_set()
>>> CID
1475954: Error handling issues (CHECKED_RETURN)
>>> Calling "kernel_getsockname" without checking return value (as is done elsewhere 8 out of 10 times).
233 kernel_getsockname(clcsock, (struct sockaddr *)&addrs);
Add the return code check in smc_clc_prfx_set().
