mesa: Fix incorrect access parameter passed to MapBuffer

The code previously passed GL_DYNAMIC_DRAW for the access parameter.
By inspection, I believe that all drivers would treat this as
GL_READ_WRITE because it's not GL_READ_ONLY and it's not
GL_WRITE_ONLY.

It appears the i965 code wants GL_WRITE_ONLY (it's about to write a
bunch of data in, never read data), while the arrayelt code is
GL_READ_ONLY (just dereffed as arguments to CALL_Whatever*v).
