Remove incorrect file reference in comment.
Commitb7eda3e moved XidInMVCCSnapshot() from tqual.c into snapmgr.c,but follow-up commitc91560d incorrectly updated this reference. Wecould fix it, but as pointed out by Daniel Gustafsson, 1) the reader caneasily find the file that contains the definition of that function, e.g.by grepping, and 2) this kind of reference is prone to going stale; solet's just remove it.Back-patch to all supported branches.Reviewed by Daniel Gustafsson.Discussion:https://postgr.es/m/CAPmGK145VdKkPBLWS2urwhgsfidbSexwY-9zCL6xSUJH%2BBTUUg%40mail.gmail.com
