freedreno: allow ctx->batch to be NULL

This was mostly true already, now that we use `fd_context_batch()` for
first access to batch in draw/clear/grid paths.  So we can drop the old
code in `batch_flush()` that tried to prevent `ctx->batch` from being
NULL.

Fixes a crash with a large number of tabs in chromium.

radv: Do not set SX DISABLE bits for RB+ with unused surfaces.

The extra bits in CB_SHADER_MASK break dual source blending in
SkQP on a Stoney device. However:

- As far as I can tell, some other dual source blend tests are passing
  before and after the change.
- A hacked around skqp passes on my Vega desktop and Raven laptop
- Getting Skqp to give any useful info or to run it outside of Android
  on ChromeOS is proving difficult.

I have confirmed 3 strategies that seem to work:
- The old radv behavior of setting CB_SHADER_MASK to 0xF
- AMDVLK: CB_SHADER_MASK = 0xFF, and the 3 RB+ regs
  are 0.
- radeonsi: CB_SHADER_MASK = 0xFF, but does not set DISABLE
  bits in SX_BLEND_OPT_CONTROL for CB 1-7.

Let us use the radeonsi solution as that solution also seems like the correct
thing to do for holes. I have tested on my Raven laptop that setting the high
surfaces to not disabled and downconvert to 32_R does not imply a performance
penalty.
