ALSA: hda/senary: Fix beep error handling and optimize EAPD switching
This patch addresses a potential state inconsistency bug and optimizes runtime performance: 1. Fix error handling in set_beep_amp(): Previously, beep_nid was assigned before adding kcontrols. If kcontrol creation failed, the function returned error but left beep_nid set, causing inconsistent driver state. Moved the assignment to the end of the function. 2. Optimize senary_auto_turn_eapd(): Removed the redundant snd_hda_query_pin_caps() check inside the loop. The target pins are sourced from spec->eapds, which is strictly filtered during the initial parse phase. Checking capabilities again during every mute/unmute hook is unnecessary overhead.
