[Mesa-dev] [PATCH v2 4/5] anv: Add missing error-checking to anv_CreateDevice (v2)

[Mun Gwan-gyeong]

This patch adds missing error-checking and fixes resource leak in
allocation failure path on anv_CreateDevice()

v2: Fixes from Jason Ekstrand's review
  a) Add missing destructors for all of the state pools on allocation
     failure path
  b) Add missing destructor for batch bo pools on allocation failure path
