radeonsi/gfx10: fix main_shader_part_ngg_es memory leak

Indeed, main_shader_part_ngg_es was not freed.

For instance, this issue is triggered on a radeonsi/gfx10 gpu with
"piglit/bin/arb_gpu_shader5-tf-wrong-stream-value -auto -fbo":
Direct leak of 1464 byte(s) in 1 object(s) allocated from:
    #0 0x7f17904b99a7 in calloc (/usr/lib64/libasan.so.6+0xb19a7)
