anv: fix calculation of buffer size in case dynamic size is used

Browse Source 
VK spec got clarification about the pSizes parameter.

Fixes set of new tests:
   dEQP-VK.pipeline.extended_dynamic_state*with_offset*

v2: move offset subtract to be part of size calculation (Jason)

CC: mesa-stable
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3871
Fixes: b9a05447a1 ("anv: dynamic vertex input binding stride and size support")
