util/hash_table: Fix hashing in clears on 32-bit

Some hash functions (eg. key_u64_hash) will attempt to dereference the
key, causing an invalid access when passed DELETED_KEY_VALUE (0x1) or
FREED_KEY_VALUE (0x0).

When in 32-bit arch a 64-bit key value doesn't fit into a pointer, so
hash_table_u64 internally use a pointer to a struct containing the
64-bit key value.

Fix _mesa_hash_table_u64_clear() to handle the 32-bit case by creating a
temporary hash_key_u64 to pass to the hash function.
