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

commit 7904022decc260a19dd65b56ac896387f5da6f8c upstream.

These variables are printed on the error path if match_int() fails so
they have to be initialized.

Fixes: 2958a995edc9 ("block/rnbd-clt: Support polling mode for IO latency optimization")
Fixes: 1eb54f8f5dd8 ("block/rnbd: client: sysfs interface functions")
