Aleksei Gimbitskii 4feeea1d8d drm/i915/gvt: Use snprintf() to prevent possible buffer overflow. 
For printing the intel_vgpu->id, a buffer with fixed length is allocated
on the stack. But if vgpu->id is greater than 6 characters, the buffer
overflow will happen. Even the string of the amount of max vgpu is less
that the length buffer right now, it's better to replace sprintf() with
snprintf().

v2:
- Increase the size of the buffer. (Colin Xu)

This patch fixed the critical issue #673 reported by klocwork.
