[ndctl PATCH] ndctl, test: add start/wait scrub to injection tests

[Vishal Verma <vishal.l.verma@intel.com>]

A number of tests that perform error injection were missing the
start/wait scrub workaround needed for nfit_test namespaces, causing
these tests to ocassionally fail. Fix it by starting and waiting for a
scrub after injection in these remaining places.
