misc: bh1770glc: use pm_runtime_resume_and_get() in power_state_store
pm_runtime_get_sync() may increment the runtime PM usage count even if the
resume fails, which requires an explicit pm_runtime_put_noidle() to balance
it. This driver ignored the return value, risking a usage-count leak on
resume failure.
Replace it with pm_runtime_resume_and_get(), which returns 0 on success and
a negative errno on failure, and only increments the usage count on success.
This simplifies the error path and avoids possible leaks. Also check for
errors explicitly with `if (ret < 0)`.
