[PATCH v2 03/11] drm/panel: s6e3ha8: Really assert reset on the failure

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

From: David Heidelberg <david@ixit.cz>

Due to incorrect implementation 0 == asserted, thus when driver fails it
needs to assert reset.

Minimal fix for stable; the polarity convention is corrected properly
later in this series.
