The anv_batch_set_error() helper will track the first error that happened
while recording a command buffer. The helper returns the currently tracked
error to help the job of internal functions that may generate errors that
need to be tracked and return a VkResult to the caller.
We will use the anv_batch_has_error() helper to guard parts of the driver
that are not safe to execute if an error has been generated while recording
a particular command buffer.
