LU-16168 tests: fix get_slave_nr in sanity-quota

Redirect output of wait_update_facet in get_slave_nr
to /dev/null/. Otherwise if wait_update_cond prints
something while waiting, get_slave_nr returns this
output together with slave number causing test_68
to fail.

Test-Parameters: trivial testlist=sanity-quota
Test-Parameters: testlist=sanity-quota fstype=zfs
Fixes: 83dd308db5 ("LU-15460 test: wait quota pool to be prepared")
