i965: Remove redundant (and uninitialized) field vec4_generator::ctx.

We never noticed that this field was uninitialized because it is only
used in an error path that reports internal Mesa errors.

But it's silly to have it around anyway because &brw->ctx is
equivalent.

Should fix Coverity defect CID 1063351: Uninitialized pointer field
(UNINIT_CTOR) /src/mesa/drivers/dri/i965/brw_vec4_emit.cpp: 148
