radv: fix pipeline stats mask

Browse source 
Left-shifting by 11*8 or 14*8 is undefined.  This fixes many
dEQP-VK.query_pool.statistics_query.* failures (but not pre-existing
flakes) for release builds using clang.

Fixes: 48aabaf225 ("radv: do not harcode the pipeline stats mask for query resolves")
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27651>
