drm/amdgpu: use idr_init_base() to initialize mgr->ctx_handles
idr_init_base(), implemented by commit 6ce711f27500 ("idr: Make 1-based
IDRs more efficient"), let us set an arbitrary base other than
idr_init(), which uses base 0.
Since, for this IDR, no ID < 1 is ever requested, using
idr_init_base(&idr, 1) avoids unnecessary tree walks.
