[PATCH] Check session->msg at sync_getphonebook_callback()

["wu.zheng" <wu.zheng@intel.com>]

Fix the issues of code style. Check session->msg at sync_getphonebook_callback()in client/sync.c. Otherwise, session->msg will be NULL and cause segmentation fault error. The reason is that the condition of transfer->fd > 0 && session->msg is ok and session->msg will be set to NULL in the func of session_notify_progress when sync profile is used.
