    fix program delete/refcount bug
    
    cherry-picked from gallium-tex-surfaces

commit 62f96ddbbc2549bd4d50016f571cd4d1f6f6a7d6

    Fix program refcounting assertion failure during context tear-down
    
    When purging the program hash table, the refcount _should_ be one since
    the program is referenced by the hash table.  Need to explicitly set to
    zero before calling delete().
    
    Also, purge high-level shader hash tables before low-level program hash tabl
    
    cherry-picked from master
