vulkan: do not map zero-sized region of memory

Browse Source 
The Vulkan 1.2 specification, section 11.2.12 ("Host Access to Device
Memory Objects") say the following:

> If size is not equal to VK_WHOLE_SIZE, size must be greater than 0

So, mapping a zero-sized range is illegal. Let's instead map the
reported size of the image, which we already know.
