Crasher fix: Use ExaDriverAlloc() to calloc the EXA struct.
Patch from Kyle McMartin. A recent exa/exa.c commit from Dave Airlie
(02ae85c4..) added a new member to the EXA struct, and corresponding
code to call it if it's non-NULL. We were using calloc with sizeof()
that struct at driver-compile-time; as a result, after the ABI change
the new member contained garbage, passed the EXA test for NULL, was
called, and segfaulted at startup.
