anv: Ignore continue flag in primary cmd buffers

Browse Source 
According to the Vulkan specification, the
VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT flag will be ignored if
included in a VkCommandBufferBeginInfo for a primary command buffer.
This also implies pBeginInfo->pInheritanceInfo should not be read even
if the flag is present, and makes it legal to include the flag knowing
it will be ignored.
