Returning early with tst_res() skips reset_sched(), leaving the process in
SCHED_DEADLINE for subsequent iterations (-i). Use tst_brk(TBROK | TERRNO,
"sched_getattr() failed") so that cleanup is triggered on failure.

Returning early on failure skips reset_sched() at the end of run(),
leaving the process in SCHED_DEADLINE for subsequent iterations (-i).
Call reset_sched() before returning.

This commit should be placed before patches 1 and 2 in the series so
that those tests can use SAFE_SCHED_SETATTR() directly upon conversion.

Verdict - Needs revision
