[PATCH 3/5] power: supply: bq257xx: Don't ignore errors from bq257xx_get_state()

The callback function bq257xx_get_state() can return an error code when
its regmap access fails, but its caller bq257xx_external_power_changed()
was ignoring those.

Return early on errors and propagate the error code to the caller.
