Use transfer queue with vkCmdFillBuffer

Due to an error in the condition, the transfer-only queue wasn't
selected for the fill buffer write operation.

Also fixed a validation error with barrier used inside a render pass
in read vertex input operation. This should have no effect on behavior.

Affects:

dEQP-VK.synchronization.op.multi_queue.*fill_buffer*
dEQP-VK.synchronization.op.*read_vertex_input*

Components: Vulkan
VK-GL-CTS issue: 481
