[PATCH] Caching service class updates during bootup.

[alokbarsode@gmail.com]

From: Alok Barsode <alok.barsode@azingo.com>

adapter->svc_cache is uses to cache service class updates during bluetoothd
bringup. adapter->cache_enable flag is used to switchoff the cache, so any successive
service class updates are directly written to the device.
