Vulkan: Fix release of semaphores in the recording context 

This seems to be a regression introduced by CL:12022, where the
previously recorded semaphores are leaked while resetting the recording
context. The Vulkan validation layers will complain about this when
running the Linux-only image wrapping tests. Also, the semaphores are
queued for deletion with the right serial now.

Bug: dawn:19, dawn:150
