tizenaudio-sink: optimize amount of 'max_request'

[Version] 5.0.154
[Profile] Common
[Issue Type] Latency improvement

tizenaudio-sink consume maximum 32ms every requesting from driver.
Therefore, I assume that the 'max_request' is able to reduce until 32ms.
This patch related with 'loopback: apply official patchset'.
