[Mesa-dev] [PATCH] Modified _mesa_align_free to have consistent behavior

[Siavash Eliasi]

This avoids accidental dereferencing of an invalid memory address by _mesa_align_free when passed pointer is NULL.

Also cleaned up different places where it was used, to avoid double check of passed pointer.

Now it is safe to pass NULL pointer to this function and expect same behavior like free().
