mesa/main: Fix GetTransformFeedbacki64 for glTransformFeedbackBufferBase
The spec has special rules for querying buffer offsets and sizes
when BindBufferBase is used, described in the OpenGL 4.6 spec,
section 6.8 Buffer Object State:
"To query the starting offset or size of the range of a buffer
object binding in an indexed array, call GetInteger64i_v with
target set to respectively the starting offset or binding size
name from table 6.5 for that array. Index must be in the range
zero to the number of bind points supported minus one. If the
starting offset or size was not specified when the buffer object
was bound (e.g. if it was bound with BindBufferBase), or if no
buffer object is bound to the target array at index, zero is
returned."
Transform feedback buffer queries should follow the same rules, since
it is the same case for them. There is a CTS test for this.
Fixes:
KHR-GL45.direct_state_access.xfb_buffers
