Subject: [PATCH 08/13] staging/android: remove size arg of sync_timeline_create()

From: Gustavo Padovan <gustavo.padovan@...labora.co.uk>

After we removed sw_sync_timeline this arg has not been really used by
anyone, all its users pass the size of struct sync_timeline there.

So simplify this function but not requiring the size anymore.
