From Gen8 onwards we apply ctx workarounds using special batch buffers that
execute during context save/restore, good to have them in error state.

v2: use wa_ctx->size and print only size values (Mika)
v3: simplify conditions when recording and freeing object (Chris)
v4: resolve checkpatch errors (Tvrtko)

It was previously sent as part of a series, now extracted as only this one
got reviewed so far.

Revision history https://patchwork.freedesktop.org/patch/75095/

Need to wait for BAT again.
