[Mesa-stable] [PATCH 3/4] meta/blit: Restore GL_DEPTH_STENCIL_TEXTURE_MODE state for GL_TEXTURE_RECTANGLE

From: Ian Romanick <ian.d.romanick at intel.com>

Commit c246828c added the code to save and restore the stencil
texturing mode.  The restore, however, was erroneously inside the
'target != GL_TEXTURE_RECTANGLE' block.

Fixes piglit test 'arb_stencil_texturing-blit_corrupts_state
GL_TEXTURE_RECTANGLE'.
