protocol: do not change pending x and y when attaching a buffer

Browse Source 
Attaching a buffer with interface version 5 requires clients to pass
zero to x and y but it still affects the pending surface state.
Attaching a buffer after a request to offset therefore sets the pending
x and y to zero. The intent of version 5 was to allow exactly this
sequence of requests to work so let's just make sure the protocol
actually spells it out.

When the bound wl_surface version is 5 or higher, passing any
non-zero x or y is a protocol violation, and will result in an
'invalid_offset' error being raised. To achieve equivalent semantics,
use wl_surface.offset.
'invalid_offset' error being raised. The x and y arguments are ignored
and do not change the pending state. To achieve equivalent semantics,
use wl_surface.offset.
Surface contents are double-buffered state, see wl_surface.commit.
