Bluetooth: Give PBAP permission only if device is AUDIO_VIDEO_HANDSFREE

Step by step:
1. Pair and connect with BTHS (e.g. SBH50).
2. Click the settings icon of paired device, and check "Use for" items.
-----------------------------------------------------------------
Expected Result:
After step 2, "Contact sharing" should not be checked.

Actual Result:
After step 2, "Contact sharing" is checked.

Fix:
Set phone book permission as REJECTED if class of Device is
not AUDIO_VIDEO_HANDSFREE

Test: Checked above usecase and issue is not observed
