drm/i915: Use i915_gem_context_get_eb_vm in ctx_getparam

Browse Source 
Consolidates the "which is the vm my execbuf runs in" code a bit. We
do some get/put which isn't really required, but all the other users
want the refcounting, and I figured doing a function just for this
getparam to avoid 2 atomis is a bit much.
