i965/gen4: Fix memory leak each time compile_gs_prog() is called.

Commit 774fb90db3e83d5e7326b7a72e05ce805c306b24 introduced a ralloc context to
each user of struct brw_compile, but for this one a NULL context was used,
causing the later ralloc_free(mem_ctx) to not do anything.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=55175
NOTE: This is a candidate for the stable branches.
