lima: fix NULL pointer dereference on error path in lima_context_destroy

When the following code path happens:
|-> lima_submit_create
    |-> drmSyncobjCreate: can fail here
    |Thus ctx->pp_submit and ctx->gp_submit are NULL
    |-> lima_context_destroy
        |-> lima_submit_free: will access submit->in_sync_fd

It triggers a segfault in mesa because we are trying to derefence
both ctx->pp_submit and ctx->gp_submit which are NULL.
