i965/miptree: Check tex image allocation failures

allowing graceful failure instead of crash on assert later on.

This can be hit, for example, on SNB when trying to allocate
8kx8k CUBE_MAP against isl: x-tiled buffer size becomes
2421161984 exceeding the maximum of 1 << 31 == 2147483648.

Another way to hit this on SNB is with multisampling of over
64-bit formats.
