etnaviv: flush all pending contexts when accessing a resource with the CPU
When setting up a transfer to a resource, all contexts where the resource
is pending must be flushed. Otherwise a write transfer might be started
in the current context before all contexts that access the resource in
shared (read) mode have been executed.

different pipe_context's)
