LU-11556 tests: fix set_persistent_param_and_check breakage

Since patch https://review.whamcloud.com/30087 "LU-7004 tests: move
from lctl conf_param to lctl set_param -P" was landed, there are
a few places that call set_persistent_param_and_check() with a node
name as an argument instead of a facet.

Fix the few places that are doing this.  Note that the call to
t32_verify_quota() is not enabled in this patch because of LU-11558,
since it is entirely possible that this code is currently broken.
This patch is about fixing set_persistent_param_and_check() breakage,
and t32_verify_quota() re-enablement can be done in a second patch.
