radv: Flush before vkCmdWriteTimestamp() if needed

As done for vkCmdBeginQuery() already. Prevents timestamps from being
overwritten by previous vkCmdResetQueryPool() calls if the shader path
was used to do the reset.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108925
Fixes: a41e2e9cf5 ("radv: allow to use a compute shader for resetting the query pool")
