[PATCH] drm/bridge: anx7625: Fix edid_read break case in sp_tx_edid_read()

[Hsin-Yi Wang]

edid_read() was assumed to return 0 on success. After
7f16d0f3b8e2("drm/bridge: anx7625: Propagate errors from sp_tx_rst_aux()"),
the function can return >= 0 for successful case. Fix the g_edid_break
condition in sp_tx_edid_read().
