LeAudio: Fix late LeAudio connect of ASHA/LeAudio HS

Fix for following scenario:
1. Connect/Pair 1 set member of LeAudio/ASHA hearing aid
2. Toggle LeAudio switch to use LeAudio
3. Connect second set member.

Issue would be that second member will use ASHA.

Since this issue will is visible when flag:
leaudio_quick_leaudio_toggle_switch_fix is enabled,
lets use it in description
