Archit Taneja f2cff0f34f drm/omap: gem sync: wait on correct events 
A waiter of the type OMAP_GEM_READ should wait for a buffer to be completely
written, and only then proceed with reading it. A similar logic applies for
waiters with OMAP_GEM_WRITE flag.

Currently the function is_waiting() waits on the read_complete/read_target
counts in the sync object.

This should be the other way round, as a reader should wait for users who are
'writing' to this buffer, and vice versa.

Make readers of the buffer(OMAP_GEM_READ) wait on the write counters, and
writers to the buffer(OMAP_GEM_WRITE) wait on the read counters in is_waiting()
