st/dri: Clear drawable texture_mask in dri2_invalidate_drawable

This makes sure that dri_set_tex_buffer2 -> dri_drawable_validate_att
will re-create the front left attachment buffer after the drawable got
invalidated.

Fixes window contents not updating until the window is resized when
using DRI2 PRIME.
