mesa/bufferobj: fix atomic offset/size get

When I realigned the bufferobj code, I didn't see the getters
were different, realign the getters to work the same as ssbo.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103214
Fixes: 65d3ef7cd (mesa: align atomic buffer handling code with ubo/ssbo (v1.1))
