SDP: Increase heap buffer size used for A2DP/AVRC

This buffer is used to save the attributes parsed from the SDP response
transferred from a peer device.

In Android O, SDP fails sometimes due to full memory from SDP DB.

The reason of this shortage seems to be the increasing of allocated
memory for tSDP_DISC_ATTR.

Android N uses a 32-bit bluetooth lib and 4 bytes of memory for
pointers.

In total, 12 bytes are used for tSDP_DISC_ATTR

Android O uses a 64-bit bluetooth lib and 8 bytes of memory for
pointers.

Now, 24 bytes are used for tSDP_DISC_ATTR.

To match this increase of memory consumption, We need to double the heap
buffer size. (from 1000 to 2000)
