small improvement

Hello

I fixed some common issues in the code. Access to moved variable is not a good idea, for example. Also several unused local variables are removed. And lost & in a function argument.

But, some expressions are really need to be clarified, they looks like some kind of issues:

1. rpcs3/Emu/RSX/VK/VKDMA.cpp (lines 52, 213)
   VK_BUFFER_USAGE_TRANSFER_DST_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT, 0);
   This is a same constants in a both sides of | operation;

2. rpcs3/Emu/Cell/Modules/cellSpursSpu.cpp:696
   ctxt->selectWorkloadAddr = isKernel2 ? CELL_SPURS_KERNEL2_SELECT_WORKLOAD_ADDR : CELL_SPURS_KERNEL1_SELECT_WORKLOAD_ADDR;
   Looks legit, but in rpcs3/Emu/Cell/Modules/cellSpurs.h:114,115
   CELL_SPURS_KERNEL1_SELECT_WORKLOAD_ADDR = 0x290,
CELL_SPURS_KERNEL2_SELECT_WORKLOAD_ADDR = 0x290,
   both constants has the same value and no comments around; That's intriguing

For VKDMA.cpp it's a typo. It should be VK_BUFFER_USAGE_TRANSFER_SRC_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT
