drm/msm/a6xx: Track current_ctx_seqno per ring
With preemption it is not enough to track the current_ctx_seqno globally
as execution might switch between rings.
This is especially problematic when current_ctx_seqno is used to
determine whether a page table switch is necessary as it might lead to
security bugs.
Track current context per ring.
