[PATCH 1/2] test: reset: Extend base reset test to catch error

[Neil Armstrong]

With this extended test, we get the following failure :

=> ut dm reset_base
Test: dm_test_reset_base: reset.c
test/dm/reset.c:52, dm_test_reset_base(): reset_method3.id == reset_method3_1.id: Expected 0x14 (20), got 0x2 (2)
Test: dm_test_reset_base: reset.c (flat tree)
test/dm/reset.c:52, dm_test_reset_base(): reset_method3.id == reset_method3_1.id: Expected 0x14 (20), got 0x2 (2)
Failures: 2

A fix is needed in reset_get_by_index_nodev() when introduced in [1].
