block/rnbd-clt-sysfs: fix a couple uninitialized variable bugs

Browse Source 
These variables are printed on the error path if match_int() fails so

Fixes: 2958a995ed ("block/rnbd-clt: Support polling mode for IO latency optimization")
Fixes: 1eb54f8f5d ("block/rnbd: client: sysfs interface functions")
